A Xerox printer grinding to a halt mid-job is one of the most disruptive things that can happen in a London office. This guide gives you the fastest, clearest path from error code to running machine, whether you manage five desks or five hundred.
This is the definitive pillar guide for Xerox error codes. It covers every major device family in Xerox’s commercial lineup including WorkCentre, VersaLink, AltaLink, and Phaser. It also links out to dedicated deep-dive cluster posts for each series. Whether you’re staring at an alphanumeric fault code on a WorkCentre 7845 or a cryptic blinking light on a Phaser 6510, you’ll find your answer here.
London businesses lose hundreds and sometimes thousands of pounds every year to printer downtime. A 2023 survey by BPIF found that the average UK SME loses 4.1 hours of productivity per printer breakdown incident. Multiply that across a busy City, Canary Wharf, or West End office and the numbers become significant very quickly.
This guide arms you with the knowledge to diagnose, triage, and fix the most common Xerox error codes in-house. More importantly, it helps you know when the issue is beyond a DIY fix and a certified Xerox engineer needs to attend.
How Xerox Error Codes Work
Xerox error codes follow a consistent logic across most of their commercial product lines. Understanding the structure means you can decode any code, even one not listed in this guide.
The Anatomy of a Xerox Fault Code
Most Xerox fault codes take the format XXX-YYY, where the first three digits identify the subsystem and the last three digits identify the specific fault within that subsystem.
| Code Prefix | Subsystem | Examples |
| 003-xxx | Paper transport / feed path | 003-340, 003-380 |
| 010-xxx | Fuser / fixing assembly | 010-310, 010-320 |
| 013-xxx | Xerographic / print engine | 013-510, 013-800 |
| 016-xxx | Scan / ADF subsystem | 016-338, 016-799 |
| 024-xxx | Laser / ROS (Raster Output Scanner) | 024-740 |
| 041-xxx | Toner / ink / developer | 041-210, 041-340 |
| 061-xxx | IOT controller | 061-370 |
| 077-xxx | Finisher / post-processing | 077-180, 077-210 |
| 116-xxx | Fuser temperature control | 116-340, 116-210 |
| 127-xxx | Network interface / connectivity | 127-210 |
Three Types of Xerox Faults
Not all error codes are created equal. Xerox categorises faults into three severity levels, and understanding which type you’re dealing with changes how you respond.
Status Messages are informational. The device continues operating. Examples include low toner warnings and waste tray near-full alerts. No immediate action is needed.
Fault Codes mean the device has stopped or degraded. Most are recoverable by the user with the right steps. These are the codes this guide focuses on primarily.
Service Required Codes indicate hardware failure. The device will not operate until a certified engineer resets the fault at the service level. Attempting DIY repairs here can void your service contract.
Important: Codes beginning with 010, 013, 024, 061, and 116 in the 300+ range almost always indicate hardware component failure. Attempting to clear these via repeated power cycles may cause further damage and could void your Xerox service agreement.
How to Read the Error Display
On most Xerox commercial devices, fault codes appear on the touchscreen control panel. Some older Phaser models display a shorter two-digit or three-digit code on an LED screen. On all VersaLink and AltaLink devices, the full XXX-YYY format is shown with a plain-language description alongside it.
The fault code is also logged in the device’s internal fault history, which you can access via the embedded web server (EWS) at the machine’s IP address. This is useful for recurring intermittent faults that disappear before an engineer arrives.
Xerox Series: Which Device Do You Have?
Xerox’s commercial line covers four main series relevant to London offices. Each series has its own quirks, common fault patterns, and repair considerations.
| Series | Type | Common London Models | Best For |
| WorkCentre | Multifunction (MFP) | 3215, 3225, 5325, 5335, 6515, 7220, 7830, 7845, 7855, 7970 | Most UK offices, widest range |
| VersaLink | Smart MFP (ConnectKey) | B400, B405, B7025, B7030, C400, C405, C7020, C7025, C7030 | SME and mid-market offices |
| AltaLink | Enterprise MFP | B8045, B8055, B8065, B8075, C8030, C8035, C8045, C8055, C8070 | Law firms, finance, NHS trusts |
| Phaser | Single-function printer | 3260, 3330, 6510, 6515, 3600, 4510, 6180, 6700 | Small offices, print-heavy depts |
The 20 Most Common Xerox Error Codes in London Offices
Based on service call data from London-area Xerox engineers, these are the fault codes that appear most frequently across all device families.
| Error Code | Description | Severity | DIY Fix? |
| 003-340 | Paper jam in fuser area (rear door) | Medium | Yes |
| 003-380 | Paper jam in exit / output tray area | Low | Yes |
| 003-350 | Paper jam in bypass / manual feed tray | Low | Yes |
| 010-320 | Fuser temperature too low during warm-up | High | Sometimes |
| 010-397 | Fuser unit end of life / replace fuser | Medium | If capable |
| 013-510 | Drum cartridge error / misread | Medium | Sometimes |
| 013-800 | CRUM chip error | Medium | Sometimes |
| 016-338 | Scanner communication error | Medium | Sometimes |
| 016-799 | Scan-to-email / SMB send failure | Low | Yes |
| 024-740 | Laser / ROS scan motor failure | High | No |
| 041-210 | Toner cartridge not recognised | Low | Yes |
| 041-340 | Waste toner container full | Low | Yes |
| 042-325 | Developer unit error | High | No |
| 061-370 | IOT communication failure | High | No |

| 077-210 | Finisher paper jam | Low | Yes |
| 091-311 | Duplex unit paper jam | Low | Yes |
| 116-340 | Fuser over-temperature error | High | No |
| 127-210 | Network / NIC error | Medium | Sometimes |
| 134-xxx | Hard drive / memory error | High | No |
Xerox WorkCentre Error Codes
The WorkCentre series is Xerox’s most widely deployed commercial MFP range in the UK. From the compact WorkCentre 3300 series to the high-volume WorkCentre 7970, these devices share a common error code architecture with some model-specific variations.
Error 003-340: Fuser Area Paper Jam
This is the number one call-out reason for WorkCentre devices across Central London. The jam occurs in the paper path immediately after the fuser, where paper exits the heat-and-pressure fixing zone.
Step 1: Power down completely. Press the power button and wait for the device to fully shut down. Do not just press the sleep button. Full power-off is essential before opening the rear door.
Step 2: Open the rear door or right side cover. On most WorkCentre models this is a hinged door on the right-hand side of the machine. It may be warm as the fuser operates at 180 to 200 degrees Celsius during printing.
Step 3: Locate and remove the jammed paper. Gently pull the paper in the direction of travel (downward on most models). Never pull against the paper path direction as this risks tearing and leaving fragments that cause repeat jams.
Step 4: Check for torn fragments. Run your hand carefully along the fuser exit rollers to check for any small torn pieces. A single 1cm fragment left behind will cause immediate repeat jams.
Step 5: Close, power on, and test print. Close the rear door firmly until you hear it click. Power on and send a 10-page test print from the machine’s internal test page function.
Warning: If the machine has been printing recently, wait at least 5 minutes after powering down before reaching into the fuser area. The fuser assembly operates at temperatures that can cause burns.
Error 010-397: Fuser Life Expired
This is a life-tracking error, not a hardware failure. The device has counted the fuser’s page yield and determined it has reached its rated end of life. On WorkCentre devices, fuser replacement is a user-replaceable procedure on most models above the 5300 series.
| WorkCentre Model | Fuser Kit Part Number |
| WorkCentre 7800 series | 115R00116 |
| WorkCentre 7500 series | 115R00076 |
| WorkCentre 5300 series | 115R00085 |
Xerox VersaLink Error Codes
VersaLink devices were introduced in 2017 as Xerox’s smart mid-market MFP range. They run the ConnectKey platform, feature a 5-inch touchscreen, and integrate with cloud services including Google Drive, Dropbox, and Microsoft 365. This introduces a new category of errors not seen on older WorkCentre hardware.
Error 016-799: Scan-to-Email / SMB Failure
This is overwhelmingly the most common VersaLink fault reported by London IT managers. It occurs when the device cannot connect to your mail server or SMB share to deliver scanned documents. It is not a hardware fault. It is a network configuration error.
Step 1: Access the Embedded Web Server (EWS). Open a browser on any networked computer and navigate to the printer’s IP address. Find the IP on the VersaLink touchscreen at Device > About > Information Pages.
Step 2: Go to Connectivity > Email > SMTP Settings. Verify the SMTP server address, port (typically 25, 587, or 465 for TLS), and authentication credentials. For Microsoft 365, Xerox requires Modern Authentication or an App Password. Basic SMTP auth was deprecated by Microsoft in October 2022.
Step 3: Test the connection. Use the EWS built-in connection test. If it fails, the error message will indicate whether it is a DNS resolution failure, authentication rejection, or timeout.
Step 4: Update firmware if needed. VersaLink devices on firmware older than 73.xx.xx may have issues with TLS 1.2 and modern certificate chains. Update via the EWS under System > Software Update.
Xerox AltaLink Error Codes
AltaLink devices are Xerox’s enterprise-tier MFPs, built for high-volume, business-critical printing environments. They are the standard choice in City of London law firms, financial institutions in Canary Wharf, and NHS trusts across Greater London. Running at 30 to 70 pages per minute, they generate different error patterns to smaller office machines.
Transfer Belt Errors (013-series)
The Intermediate Transfer Belt (ITB) on colour AltaLink devices is a high-wear component. The 013-651 code (ITB failure) typically indicates either that the belt has reached its rated life or that the belt has physically torn or delaminated.
AltaLink C8045 and C8055 devices on lease contracts in London legal offices frequently trigger this fault at around 400,000 to 450,000 colour pages. This is slightly earlier than the rated 500,000 page yield when run in humid environments such as basement print rooms.
AltaLink Finisher Errors
London firms using AltaLink devices with the BR Finisher or Booklet Maker Finisher regularly encounter staple and fold-path errors, particularly when producing large stapled document sets for legal bundles or board packs.
| Error Code | Issue | Quick Fix |
| 077-180 | Staple jam in main stapler | Open finisher front door. Remove staple cartridge. Clear jammed staple and reload. |
| 077-210 | Paper jam in finisher | Open finisher doors, follow numbered jam clearance sequence on screen. |
| 077-300 | Booklet stapler jam | Open booklet maker section. Remove booklet staple cartridge and clear jam. |
| 077-401 | Punch unit paper jam | Open punch waste unit. Clear paper fragments. Check punch waste box. |
Xerox Phaser Error Codes
The Phaser range comprises single-function printers, primarily laser, covering both colour and mono output. Phaser devices have a simpler error code structure than the MFP ranges. Most faults are displayed as short three-digit codes or plain-language messages.
Error 003-310: Tray 1 Pick Failure (Phaser 6510/6515)
One of the most common Phaser 6510/6515 errors. The pick roller in Tray 1 fails to feed paper into the print path. In the majority of cases this is caused by worn pick rollers, a common occurrence when using recycled or low-weight paper.
Step 1: Clean the pick rollers. Remove Tray 1 fully. With a lightly damp lint-free cloth, wipe the pick roller at the front of the paper path. Allow to dry completely before reinserting tray.
Step 2: Check paper stock. Fan the paper stack before loading. Avoid loading paper stored in a humid environment. Use 80gsm A4 for standard jobs.
Step 3: Replace pick rollers if cleaning does not resolve the issue. Phaser 6510/6515 pick roller kit is user-replaceable (part 115R00060). Replacement takes approximately 20 minutes.
Paper Jam Errors: Every Code, Every Location
Paper jams account for more than 60% of all Xerox service calls in London offices. The vast majority are user-clearable, but clearing them incorrectly leads to repeat jams and accelerated roller wear.
The Golden Rules of Jam Clearance
- Always follow the on-screen instructions. The device touchscreen will guide you through the exact sequence of doors to open.
- Never pull paper against the direction of travel. Always pull in the direction the paper was moving.
- Account for every piece. If you pulled out a torn sheet, find the missing fragment before powering on.
- Look for the root cause. If the same jam repeats more than twice per day, the problem is the rollers or sensors.
- Never use sharp tools inside the paper path. Tweezers and scissors can damage sensors, rollers, and the fuser.
Jam Code Reference by Location
| Code Range | Jam Location | Typical Cause |
| 003-3xx | Main paper path / fuser exit | Worn fuser exit rollers, heavy media |
| 003-35x | Bypass tray / manual feed | Incorrect paper loaded, tray overfilled |
| 003-38x | Output / delivery area | Output tray full, obstruction in exit path |
| 091-3xx | Duplex unit | Worn duplex rollers, heavy or coated media |
| 077-2xx | Finisher paper path | Edge-curl on paper, overloaded job set |
Fuser and Temperature Errors: 010 and 116 Series
Fuser errors are among the most important to diagnose correctly. A true fuser hardware failure requires a component replacement costing 150 to 450 pounds depending on the device. But many fuser codes are triggered by environmental factors or temporary sensor glitches.
Fuser Error Triage
Step 1: Power off for 30 minutes. Many 010-series errors are triggered by temporary thermistor events. A full cold power-off clears these in approximately 40% of cases.
Step 2: Check the operating environment. Xerox fusers require a minimum ambient temperature of 10 degrees and maximum 32 degrees Celsius. London offices that become very cold overnight can trigger cold-fuser errors on the first warm-up of the day.
Step 3: Power on and observe. If the error clears and the device warms up normally (2 to 4 minutes), the fault was transient. Monitor for recurrence over 48 hours.
Step 4: Check fuser page count. Access the usage report via the EWS or touchscreen under Device > Billing/Usage. If the fuser has exceeded its rated yield, replacement is due.
Step 5: If error persists, call an engineer. Persistent 010-310, 010-320, or 116-340 errors indicate a failed thermistor, heating lamp, or pressure roller assembly requiring certified repair.
Network and Connectivity Errors
Since most London offices run Xerox devices on corporate networks with Active Directory and Microsoft 365, network-related error codes have become one of the fastest-growing fault categories, particularly since Microsoft’s deprecation of Basic Authentication.
Key Network Error Codes
| Error Code | Issue | Quick Fix |
| 016-799 | Email / SMB send failure | Update SMTP auth settings. Modern Auth required for M365 since October 2022. |
| 016-404 | LDAP directory lookup failure | Check LDAP server address, port (389/636 for LDAPS), and bind credentials in EWS. |
| 016-503 | FTP / SMB scan destination unreachable | Verify scan-to-folder destination path, user permissions, and SMB version. |
| 127-210 | NIC / network interface error | Check Ethernet cable, switch port, and network VLAN assignment. |
Microsoft 365 Scan-to-Email Fix
For VersaLink and AltaLink devices scanning to Microsoft 365, use SMTP relay via a static IP range or configure OAuth 2.0 Modern Authentication. The legacy SMTP username and password method no longer works unless you have explicitly re-enabled Basic Auth in your tenant, which Microsoft may disable without notice. Consider switching to Scan-to-SharePoint via an app connector instead.
Toner and Drum Errors
Toner-related errors are among the easiest to resolve but also among the most frequently misdiagnosed. The rise of compatible and remanufactured toner cartridges has introduced errors from Xerox’s CRUM chip system specifically for non-Xerox consumables.
041-210: Toner Cartridge Not Recognised
This error almost always indicates one of three causes: a non-genuine toner cartridge, a poorly seated cartridge, or a faulty CRUM chip on a genuine cartridge.
Step 1: Remove and re-seat the toner cartridge. Open the toner access door, remove the indicated cartridge, and reinsert firmly.
Step 2: Clean the CRUM chip contacts. Using a dry lint-free cloth, gently wipe the gold-contact CRUM chip on the side of the cartridge.
Step 3: If using compatible toner, check compatibility. The chip may not be correctly programmed for your device’s firmware version.
Note: Using non-Xerox toner in devices under a Xerox service contract may give Xerox grounds to decline a service call if a fault is attributable to the consumable.
Preventive Maintenance: Stopping Errors Before They Start
The most cost-effective Xerox fault code is the one that never appears. For London offices, particularly those in older buildings with variable humidity and dusty environments, a structured preventive maintenance routine dramatically reduces unplanned downtime.
Monthly Maintenance Checklist
- Clean the document glass and ADF feed rollers. This prevents scan quality issues and 016-series errors.
- Fan and reload all paper trays. This prevents clumping and feed errors. Replace paper sitting in trays over 2 weeks.
- Check waste toner container fill level. The 041-340 error stops the device completely when full.
- Verify network connectivity and firmware version. Check EWS for available updates.
- Review the fault history log. Recurring self-clearing faults are early warning signs of component wear.
Quarterly Maintenance Checklist
- Clean or replace pick rollers, particularly on high-volume trays. A 15 pound roller kit avoids a 200+ pound service call.
- Check fuser page count against rated yield. Order replacement before the error appears.
- Test all scan destinations. Verify scan-to-email, scan-to-folder, and scan-to-SharePoint still work.
- Inspect ADF separator pads. Worn pads cause multi-feeds and misfeed errors.
When to Call a Xerox Engineer in London
Knowing when not to attempt a DIY fix is just as important as knowing the fixes. These error codes signal that a certified Xerox engineer should attend.
| Error Code | Why You Need an Engineer | Typical London Cost |
| 024-740 | ROS/laser unit failure. Requires laser assembly replacement and calibration. | 350 to 600 GBP |
| 061-370 | IOT board failure. Main controller board replacement. | 400 to 900 GBP |
| 042-325 | Developer unit failure. Developer assembly replacement plus calibration. | 200 to 450 GBP |
| 116-340 | Fuser over-temperature. Fuser replacement, thermistor testing, safety inspection. | 180 to 380 GBP |
| 134-xxx | HDD/SSD failure. Data security implications, replacement required. | 250 to 500 GBP |
| 013-800 | Persistent CRUM errors indicate NVRAM or IOT board issue. | 200 to 400 GBP |
Xerox’s own service covers most of Central and Greater London with a 4-hour response SLA on Priority 1 devices under contract. Independent Xerox-authorised engineers typically offer same-day or next-morning response for EC, WC, E, N, SW, SE, and W postcodes. For the M25 outer ring, allow 24 hours.
Final Word
The most effective approach to Xerox error codes in a London office is not to treat this guide as a one-time lookup table. Use it as part of a proactive printer maintenance plan. Document the error codes your Xerox device shows, note the page count when faults appear, and replace high-wear parts such as rollers, fusers, drums, and transfer belts before they cause major downtime.
However, not every Xerox fault should be handled in-house. If your printer keeps showing the same error code, will not clear after basic troubleshooting, or displays a service-level fault such as a fuser, laser, developer, or controller error, it is safer to get professional support.
At London Printer Repairs, our experienced engineers provide Xerox printer repairs, servicing, and maintenance across London and inside the M25. Whether your office is dealing with paper jams, toner faults, fuser errors, network issues, scan-to-email problems, or a completely locked Xerox machine, we can diagnose the fault and help get your printer working again quickly.

Frequently Asked Questions
What does Xerox error code 116-340 mean?
Error 116-340 indicates a fuser over-temperature condition. The fuser has exceeded its safe operating temperature threshold. This is a safety-critical fault that prevents the device from operating. It can be caused by a faulty thermistor, a failed fuser control board, or in rare cases a genuine overheating event. Power off immediately and contact a Xerox engineer.
How do I clear a Xerox fault code permanently?
User-clearable fault codes (paper jams, toner errors, connectivity errors) clear automatically once the underlying issue is resolved. Service-level fault codes require a certified engineer to access the device’s diagnostic mode and perform a fault reset after confirming the hardware is in a safe state.
Can I use third-party toner in my London office?
You can, but consider three things. First, Xerox’s CRUM chip may display warnings or reduce print quality settings. Second, non-genuine supplies under a service contract may void support for consumable-related faults. Third, quality varies enormously so use a reputable UK supplier and verify chip compatibility with your firmware version before bulk purchasing.
My Xerox keeps showing the same paper jam error. Why?
Repeat jams in the same location almost always indicate a worn pick roller, feed roller, or separator pad. Once these rubber components wear smooth or harden with age, they can no longer reliably grip paper. Cleaning with a damp cloth gives temporary improvement, but replacement is the proper fix. Roller kits cost 15 to 45 pounds and are user-replaceable.
How do I access the Xerox error log?
Access the Embedded Web Server by entering the device’s IP address into a browser. Navigate to Support > Fault History. This log records every fault code with timestamps and page counts, which is invaluable for diagnosing intermittent faults.
Should I repair or replace an old Xerox WorkCentre?
If the estimated repair cost exceeds 50% of the replacement value, replacement becomes competitive. This is especially true when factoring in improved energy efficiency, security features, and remaining support. Ageing WorkCentre 5300 and 7500 series devices with persistent IOT or ROS errors are often better replaced with a VersaLink or AltaLink on a managed print contract.
