Thank you for your response. I'll do the test patterns as soon as I get back to the office

As for the cost, that's what they deem to be a full service,

Re: C550, I'm seeing faint spots when printing pastel colours

have seen this before, are you using oem toner? what is the actual count on your developer units. this can be caused by damage to the developer sleeve. (usually caused by somebody with a vacuum). i would do the charts to determine what units are causing the problem. have seen aftermarket toner grind the coating from the developer sleeve.

Thank you for your response. I've always used oem toner. To be honest I did look in to buying after market toner, But couldn't justify the cost. Its cheaper to buy genuine.

I should mention one of the reasons I moved away from xerox was that I could just call an engineer. Looks like I'm back to square one. Finding a solution to my problem.

Problem with the count on the developer is for some reason the engineer didn't reset it. I asked him why, he mentioned that they keep a full log of what's done on all jobs/machines on internal system.

I see a repetitive defect. What's the interval? =^..^=

Go into the service mode and print test pattern 53 (if i remember correctly) and change the cyk to 0 and the m to 80
and see if the spots appear, and then do the same for the other colours this should then show if its 1 particular colour causing the problem. load up your results.

Hi Gaffers

I don't blame you if you want to virtually slap me silly.

I have printed test patterns in the past, however I cant seem to do it now, my mind is completely blank. I manage to get in to service mode by soft booting holding down utilities/ test pattern Mode. I even enter all the information

Pattern 53
Y /0
M /80
C /0
K /0

What do I do next to actually get the machine to print the pattern, pressing start doesn't work. WhatsApp Image 2019-03-19 at 17.45.15.jpg

Haha no problem, there should be a Copy Screen button at the bottom If I remember which will take you back to the screen you would normally see and you then make sure that colour is selected and which tray you want to print from. And then when printed press the button at the bottom right to return back to the test pattern screen.
