Ricoh IS450DE Scanner

Verify the OPC drum and the polygon motor scanner glass,something is dirty.

Hi,
if you have already cleaned all the areas in scanner, then the reason should be an error in your scanner interface cable. This is the flat, grey cable which is connected to scanner lamp. Try to disconnect it and connect it again. When you use your Canon just for printing, there should be no dark lines.
Also maybe you scanner lamp has a problem. These things you can't repair.
Good luck

Does this happen when you print, or only when you copy? If you print out a configuration or user settings page, or print a page from the computer, is it also missing two vertical lines of print or is it only when you are copying?

If it happens when you print, you may need a cleaning, or you may need to replace the toner or drum cartridge. If it's an inkjet machine, there's a possibility there is some ink or grease on the encoder strip (a small belt-like plastic strip that goes through the print-head carriage).

If it only happens when you copy, test both the flatbed and the document feeder. If it happens on both then you may have a bad scanner. If it only happens when using the document feeder, you likely have some whiteout (or something) on the glass. When you make a copy in the flatbed, the scanner moves across your document. When you make a copy using the document feeder, the document moves across the scanner. In this case, if there is anything on the scanner glass (like whiteout) your copies will be missing a vertical line of print data (it could be white if there is whiteout on the glass, or it could be dark if something dark is on the scanner glass).

Usually you can lift the flatbed cover and look at the glass to see if anything is on it (usually at the left side of the scanner). Clean the glass, first with alcohol to remove the obstruction, and then with a little windex to remove anything the alcohol may have left behind.

Please clean the glass. The lines are because of dirt on the glass. Pls dont use solvents.

Try cleaning the rubber rollers in the ADF

Dust in the scanner, clean the scanner line inside the refill  compartment

The bulb has nothing to do with the paper feeder.
Open the door and ther has three or to tires or rubbers so clean them with glass cleaner or 98% alcohol if after that dose not feed again you should replace the feed rubbers

Clean the optical path. Remove glass and use very fine quality micro fiber cloth with no cleaning agents to wipe mirrors and glass. reassemble and test. If no better then maybe focus is off!

If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.

The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.

Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.
