I'm using a Canon imageclass MF4880dw laser printer. The problem started when toner spilled into the machine. The ink pattern has changed as I've tried to clean the machine, but I'm not sure which part is causing this to happen, especially since I'm pretty sure it's outside the printable zone. I've tried different toner cartridges and took as much of the machine apart as I could figure out how to (though not quite as much as I would have liked to have to thoroughly wipe down the rollers). The blobs are darkest on the first page printing and then get lighter with subsequent pages, but then are dark again if I start a new print job. I'm almost to the point of just getting a new printer since I've been thinking about investing in a color laser printer, but still this printer is perfectly good.
I will be glad to assist you.
I recommend performing a cleaning of the fixing unit. To perform the cleaning, please follow the instructions below:
