Error code 31 on a konica royal 1500 ''paper mishandled''.
I removed all feed rollers and feed belt to clean and rough up surfaces but it still faults out with error 31. Sometimes it will work using manual feed tray. However, it still gives fault 31 most of the time. I wonder if there is a timing issue when removing the feed roller assembly.

Re: error code 31 on a konica royal 1500 ''paper...
Have you replaced the paper pick up & paper feed & paper sep. rollers? Also, have you cleaned the paper pick up clutch? The reason it works with the manual feed is that it is not used as much. Also, have you cleaned the rollers with wd-40 or simple green and did it work better, if so you need new rollers. Good Luck

Use a little water on grab rollers to see if that helps. If it does use a scrubby to roughen same. This is if the grab or feed rollers have become polished from use and lost the gripping surface. If the issue is after the feed rollers a motor or belt may be the problem inside and after the first feed roller.
Pickup rollers suffer from several possible faults-
- Cheap paper can lose fibers that clog the roller reducing friction
- Rollers can harden, reducing their 'stickiness'
- The slightly roughened surface of the roller loses its roughness
Sometimes the roller will improve with cleaning but don't use alcohol since this will leach softeners from the roller so a mild detergent is better such as window cleaner and a fiber-free cloth; you don't want to worsen the problem.
Some mfr.s (HP for one) have produced short-lived rollers that required 'roughening' pads and a small program to drive the roller for seconds to minutes to restore the minute 'fingers' to the roller.
If a high-usage printer, you may have to replace the pickup roller and the labor involved varies greatly.
One 'quick and dirty' method that sometimes works is to reset the paper length to 'legal' (runs longer) and put a good quality paper sheet that has been wetted with window cleaner in the feed slot and allow the roller to rotate on that surface by holding the end of the sheet.
The printer will eventually error out with a 'misfeed' that may require resetting.
Allow it to dry again before trying to print.
Clean the pickup roller(s) (in the paper tray) with mild soap and water if you can remove the pickup roller easily or with a q-tip if you can't. DO NOT USE alcohol as it will dry out the pickup. Use at least two q-tips, don't stop cleaning too soon. You can use a little fine steel wool to rough up the roller surface too. Replace the rollers if that doesn't work. Usually cleaning them is a stop gap measure. This works for the top rollers too.
Try the following: take an A4 sheet of paper and glue a 2 - inch strip of sanding paper onto the top of the sheet (full width of the page). sanding paper should be about 120 grain.
Now feed the page with the sand paper first (rough surface on top) into the paper inlet. grab and hold the paper, then press paper feed or send a print job. The printer tries to feed you special sheet, but you won't let go. This will sand off the gunk from you feed rollers and give a bit of rough surface to the rubber. Repeat if needed, it should cure the problem.
This works if the problem is the roller surface, it will not fix a problem with misalignment or a missing/broken spring in the feed roller mechanism.

Had the same problem with mine, very intermittent. Remove all the paper and open the feed tray lid so you can get access to the three grey pinch rollers. Start printing then push on the roller with your finger to try and 'rough it up' (if it clicks you are pressing too hard).
The fault appears to be that the pinch rollers are loosing their grip and can not pull the glossy paper through. I dare say using a mild washing up liquid solution would be better but this is a safe quick fix.
Did this to mine and it has worked fine ever since.
Can you be more specific about which canon copier you have. There are different feed rollers in different copiers. A short term fix is to clean the feed rollers. You will have to remove or remove the paper tray(s). depending on which copier you have. Some type of dry cloth (free of any residue/I use white dry shop towels) and a little rubbing alcohol will usually get you going again. You should be able to see the feed roller. Just clean it all the way around the roller. Use the alcohol sparingly, you don't want any liquid dripping inside of your copier.
The feed rollers also wear out. Once they get to smooth, they may no longer pick up the paper. If the rollers are removable, some just snap out, you can even lightly rough up the surface with a really fine emory cloth.
Feed rollers wear out and eventually reach a point where they must be replaced. The more card stock that you run through your copier, the fast they wear out.
Hope this helps. If you look inside and are confused what the feed roller is, then your best best is to call a copier repairman.
''grabber'' roller out of work sometimes, you may try
1) there is a input paper sensor around roller, the roller out of runing if the sensor is not senitive enough or sensor switch dirty,
clean the sensor as you can find it,
2) Lighter-weight paper feeds and prints fine, which means this paper input sensor works ok, but you need to make sure they are same paper input sensor,.
3) the paper surface bright and the roller worn could be cause paper feed fail, you need clean the roller anyway. still not fixed, you need to adjust the roller pressure by increase the spring force.`
I have the same printer and had the same problem.
Cleaned takeup roller wit isopropyl and it has worked now for 18 months. If you dont use it often, remove top sheet from stack and blow the dust off it before printing.
