Question about HP Color LaserJet 3500 Printer
Prints well, except that the left side of each page is devoid of black. The right side is excellent black and color. Color is good on entire page, but there is a fade from the good right side black to no black on the left. There is no paper blocking the image, and I've substituted known good black cartridge and ITB from working CLJ 3500 printers in the building, same problem exists. Replaced the image drive assembly, RK2-0248-000CN, and added the washer to the shaft that HP recommends to prevent rattling or noisy black developer clutch sounds, XD1-1108-229CN while I was in there. Did a cold reset, and ran calibration. Still no black on left side. Any advice would be greatly appreciated.
The folded paper solution for for me. Thanks to all for sharing!!!!
I had the same problem. No black or cyan on the left side of the pages. From this advice... I folded a stack of 4 pieces of paper in half and then half again. I took out the transfer unit and put the folded paper in the upper left corner and then put the transfer unit back in. WORKS BEAUTIFULLY! Thanks you all sooooo... much!

I would suggest you try replacing the dev unit itself. This should rectify the loss of density on the one side. If you need a service manual for assistance with changing the dev unit, try http://www.TheServiceManualShop.com they will likely have one. I presume you have also checked the laser lens to see there is no toner spilled onto it? This usually only accounts for thin areas of blank print.
