20 Most Recent Lexmark C530dn Laser Printer Questions & Answers

The error indicates that the system board's on-board memory has failed. This usually requires a service call but you can try to turn off the printer, then turn on after 15 seconds. If the problem continues, I strongly suggest you contact Lexmark technical support or an authorized service provider for assistance. You may need to know your printer's model type and the serial number when calling for service. Thanks.

When I have seen this error in the field, I have cured it by updating the firmware. Lexmark has a paper in their Knowledge Base on 900 errors:

It is probably a faulty black drum unit. I would hazard a guess that something like a corona wire or Primary Charge roller is not transfering charge to the optical drum correctly.

How old are the pcr units (drums). sounds like either a problem with the magenta drum or the magenta toner cartridge is leaking.

Don't change the density / RET on your Color Laser Printer, you can adjust when necessary from your printer driver via your computer.This Magenta issue I see often in this Lexmark Printer, replacing the toner may help, but cleaning the contacts on the transfer belt and dumping the waste hopper, is the only solution.I would only use O.E.M. Toners on this printer.

Have you replaced any components on this printer? This error happens if you replace the display, engine card or interconnect card with one from another printer. Parts are not reusable.
