We recently had a customer contact us with an unusual fault on their HP Colour LaserJet CM2320 printer. They reported intermittent banding on their printouts, with strong horizontal lines appearing in multiple colours. The image below shows that not every print had these lines, making the issue intermittent and difficult to diagnose. We carried out a thorough diagnostic assessment to identify the root cause.
Diagnostic Assessment and Solution
The diagnostic assessment included a colour print test. Initially, I suspected a fault with the formatter board. However, upon closer inspection, I noticed that some of the marks on the prints were directly related to a worn or faulty toner drum unit. We decided to replace all the toners and test the printer again. Fortunately, after replacing the toners, the printer tested perfectly.
The Benefits and Pitfalls of Compatible Toners
This customer was using compatible toners, which I generally recommend because they can save customers a lot of money. However, it’s important to note that not all compatible toners are created equal. They can vary significantly in price and quality. Here’s some advice to help you choose the best option for your needs:
- Avoid the Cheapest Options: While purchasing the cheapest compatible toners might seem like a cost-saving measure, it often leads to more problems. Some cheap toners are just old cartridges refilled with toner, while others are clones that may not perform perfectly.
- Have a Spare Set of Toners: Always keep a spare set of toners on site. If your business heavily relies on the printer, having a spare set of original toners is crucial.
- Check the Return Policy: Ensure your supplier has a good return policy for faulty toners. At London Printer Repairs, we promise to return any faulty toners with more than 20% life left, as long as a supplies page is sent to us. This helps you avoid expensive printer repair bills caused by faulty toners.
