First of all I must apologise if this has been covered before, I've done a great deal of googling while trying to understand this problem and eventually came across the wonderful wealth of knowledge on this site, however nothing I've read on here seems to describe the issue I'm having with this device. I have found a service manual online which I've purchased and should arrive in the next few days, but I thought I'd post this query here in the vain hope that it is either something simple or perhaps even something of interest to any of you!
So first a little back story, part of our business is an auction house that moves a lot of ex-office equipment, so printers, scanners, PC's, etc... We run a couple of IR3100C's in our office which are covered by a support contract and we're happy(ish) with their performance.
Recently a couple more of these devices came into our hands with the iSend functionality which would be massively useful to us (myself personally as it would remove the need for my users to scan their documents using TWAIN like network software and then convert them to PDF locally which although a simple enough process, seems to cause a lot of confusion to some people). Anyway, onto the issue.
I fired up the first IR and couldn't get it to feed a single sheet out of its drawer, I'm sure this can be rectified but I moved onto the second. I loaded one of the trays and put a test sheet in the feeder, when the print came out it had a large number of short vertical lines of variable thickness seemingly randomly placed. I figured it could be a scanning issue so I went into the menus and printed out a couple of reports successfully with no distortion. So then I hooked the thing up to a quick test network and printed a couple of Printer Test Pages out, I got good prints the first few times, but every now and then I would see similar distortion to the printed image.
Next step and onto the clincher... I took the plunge and spent 5 minutes getting the device talking to our mail system here and took a scan to my mailbox, the resulting PDF is attached (apologies, it's a whole MB, I will have to adjust the quality settings to shrink that down if I ever get to it!) the distortion on the copies is very similar to the distortion seen in the image, although the best approximation of it can be seen in the top band where the "Windows 2008" line of text should be... If anyone would like to see a copy of one of the printouts I will gladly scan that on one of our other copiers and upload it here..
Now I'm not going to go digging into this device as I really don't want to get blinded or pull something out that I really shouldn't be handling, I fully intend to let the guys that run our support contract come down and fix this if it's possible, I just don't want to have the wool pulled over my eyes by them regarding what is actually wrong with it. My initial thoughts were either bad memory as I've seen similar issues on computer displays when video card memory goes bad, hard disk failure or a loose connection somewhere... Anyway, here's hoping one of you experienced canon techs has seen this before and you can tell me it's something simple!
Apologies for the long story, if you need any more information about the device just let me know and I'll get right on it!
