Trying to troubleshoot this laser printer. The blue color drips dots now on all printed materials. Already did the two types of cleanings: Clean Fixing Assembly amd Clean Feeder. Clean ITB button refuses to start, so we are unable to get that going. Does ceylon blue tomer cartridge need changing periodically? It is leaving crumbly blue bits all over inside the machine now after the two cleans. Tried to remove the 3 cartridges and leave black inside only, but there must be a sensor telling the printer not to function due to the 3 missing cartridges. And naturally, the 3 years warranty just expired. Thanks in advance.
