C5030 copy quality

[repeatcopiers]

I have a c5030 in the field that started having faded magenta on their copies/prints. We replaced the magenta drum unit, but after about 2 weeks it started again. The tech found that the magenta drum was holding onto the toner and not laying it all on the ITB, so he swapped out the drum and developer from a C5235, it ran about 30 great copies then started again. He inspected the transfer rollers inside the ITB and they seemed fine but he went ahead and swapped the cyan and magenta to see if that changed anything but it did not. I've attached a PG10 plus some images of the drum (which we replaced twice in the beginning thinking we had a defective drum).

1. Stir Developer in service mode and see what you get: COPIER>FUNCTION>INSTALL>STIR (M)
2. Replace the developer with a working one and compare

Thanks, that information must have got lost in my long ramble. The customer has a C5235 in their office too, so we did take the drum and developer out of that machine and it gave the same result.

seeing your photos you are working with compatible drums, I would recommend that you buy and install the original CANON spare parts and consumables, so that you have a good print quality and durability

I agree. This is a COD customer and they buy their toners and drums online and just pay us to diagnose and install. They do buy OEM toners but these drums are compatibles. They use these in both of their copiers (C5030 and C5235) without any issues in the past so it would be a hard sell to make her spend money on OEM drums right now. The drums are making great copies on their C5235, we are only having issues with the C5030.

Drum and dev problems replace oem drum unit and dev unit if using cheap toner tell then to use oem on compatibles even katun can't get the magenta colour correct

I am in total agreement regarding OEM parts and supplies. But since we are swapping the drum and developer unit from the C5235 to the C5030 and getting the same result (C5235 continues to have great copies and the C5030 continues to have this issue) I feel like this is coming from somewhere else.

If you use parts from another machine it doesn't set up automatically. The pictures show cleaning problem in the drum unit if it was clean I would have said remove laser and clean but pic's defo looks faulty drum / dev units

Right, when we took a drum and developer out of the other working copier, we got about 10 or 15 decent copies before this issue started showing itself again. Plus we wiped off the excess toner on the drum and put it and the developer in the other copier and it did not present itself at all. The laser is my next guess.

It is very hard to see, but we just noticed the Yellow is doing the same thing, not easy to see on the PG10 but definitely there.

Re: C5030 copy quality

If it is on the drum and not on the ITB, I would not bother with any laser. If the laser failed, you would not have a image written on the drum. You may be having issues with primary transfer, either through the ITB or in machine contact.

hello if you have changed the magenta development unit and magenta drum unit.
What adjustments did you make in the service mode? (copier-function-install-iniset4) and adjust gradation full
