I have a canon dr 5020 that just started scanning slowly

Try this, tape it to a sheet paper.

First ensure that the SCSI card is installed properly. Download DR 5020 drivers from http://software.canon-europe.com/products/0000672.asp and install them. Use CapturePerfect ver 2 or 3 to scan documents. With SCSI based scanners/devices, one should power-on SCSI device first before starting the Computer.

When the top cover is open you get message C01, when the top portion of the top module is not in position, you get C02 error.

The Canon 5010/5020/9080c/7580C etd are duplex scanner (can scan both sides in one go). If you select simplex i.e., only top side, you will get the image straight, unless you have changed the settings in the scanning software. I am assuming you are using CapturePerfect software. Please switch off the rotate option in Capture perfect and the scanner output will be as you see it.

With the handpiece on the hook. Try typing #86 into the handset. This should turn on CLI from that handset.

CapturePerfect ver 3 is on chargeable basis! You can download ver 2.0 from http://software.canon-europe.com/software/0022439.asp?model= Though this is listed under Canon DR 5020, it works fine with DR 9080C. DR 9080C has very intelligent features and ver 2 works fine. I do not know if there are addl features with ver 3.0. I have used for scanning over 500,000 docs.

There is fuse, but in the Power supply board. Check if LEDs are blinking in the back PCB and on the right side. Do a basic check also, check if the power cable is good. many times we assume that is perfect, but not necessarily.

Wipe the rollers with a damp cloth thoroughly. Remove all the dust in the glass for a claen scan. The red color roller roller in the bottom needs thorough cleaning, rotate with hand gently (in power-off mode) and clean it thorughly. No solvents pls, except Isopropyl alcohol for cleaning
