Ricoh MPC3001 weird bright lines on photos

[DennisCarmen]

Hi everybody
Like you can see on the pictures my Ricoh MPC3001 prints weird bright lines on my photos.
It only happens on photos, for the rest, the copier prints wonderfull.
I have cleaned drums, transfer belt and even the whole laser unit.
Please advise?
Thanks Dennis.

It seems to me that the problem is in the cyan unit. I would recommend taking out the developer and straining it to eliminate any impurities that are obstructing the passage through the magnetic roller.

It could be a beginning of deterioration of the sponge gaskets of the Developer Box, I happened to have to deal with the entire unit, being disassembled to sift the dust and I had to completely rebuild it.

Did you clean the laser slit glasses?
