LaserJet 1012 Vertical Fade
Printer works well but has a "slight" faded vertical band about 3 inches
from the left margin, about 1/4 inches wide. New cartridge. Doing a "half self test" I can see slight fadeing on the drum at that location. I surmise this means some issue with the laser mirror or lenses. Normal cleaning cycle has not helped. I have the service manual and am tempted to disassemble and gently clean the lenses [soft cloth/brush] but as this somewhat involved [and I could make the problem that I can "live with" worse] I thought I should ask if (1) does my diagnosis sound right and (2) is there is any easier way to accomplish this cleaning short of complete disassembly. Thanks for any advice. |

LaserJet 1012 Vertical Fade
Possibly solved but comments still welcomed.
Before following disassembling to check the fuser sensor [which I understand can accumulate toner and leave about a 1/4 inch wide faded stripe], I removed the cartridge, depressed the laser shutter lever, and inspected the laser lens area with a dental mirror. I could not see anything on the glass, but used a blast of air. Faded vertical stripe almost invisible now. [I probably would not detect it had it not been noticable before.] So I will stop while I am ahead. "John Keiser" wrote in message ...

You can use a cotton bud if you wish to clean the lens, but it sound like you have it under control. Tony "John Keiser" wrote: Possibly solved but comments still welcomed.
