Hi everyone and thanks for letting me into your forum.
I have a CL7000 that I brought out of storage and am seeing if I can put it back in service. I gave it a good cleaning and have resolved most of the issues with one that's very vexing to which I hope someone will have some insights.
There are 2 printing issues which may be from the same problem:
- the colors are out of alignment
- it's printing a repeating candy-cane-like pattern of colors stripes (1 stripe for each color vert then one for each color diag, then repeats). on the back of the page in 3 stripes - left, middle and right. I cleaned off the transfer belt before running another test and the pattern was recreated so the printer is trying to say something to me that I don't understand and can't find reference in the service manual.
Before it was put in storage the fusing unit was replaced but I didn't do a forced realignment (having not read the manual at the time).
When I try do to an auto alignment (which is the only option) it responds:
result = NG
Does the same when I run a fusing unit alignment. I assume that means an error was detected. When I display the error code it comes up
070707
The manual indicates that is a sensor error.
I understand this printer has 2 sensors - one located at the start of the transfer belt (paper feed end) and another at the fusing unit end. There are directions to get at the one by the paper feed, which I was able to attempt to clean up, but nothing about the one at the fuser end. I took the printer apart and looked around as best as possible but didn't see anything, but it is crowded in there and might have missed something.
So I'm just about there getting this back in running shape but could use a little help from those with some experience as i'm a noob.
