Anti jam light is on unit will not run


The "anti-jam" light actually is a jam light and it is notifying you that the shredder is jammed. If you turn off the power and examine the shredding unit you will find shreds of paper stuck in the mechanism. Removing all of the shreds will get your shredder back in operation and the anti-jam/jam indicator will be off

Orange light blinking, cleared paper jam, changed printer cartridge, won't print subsequent documents.


Double check all doors/ rollers for small pieces of paper stuck in the rollers. Sometimes just opening the door in question and closing will reset the paper jam sensors. Paper jams can be smaller than your pinky finger nail. So double check,

Comment if it still isn't working.

The Lexmark x342n all in one printer gives the error code 200.20 i took out the paper jam and tried to print again but it still gives the same fault i also can the drum and tried again but it only...


General tip: If the paper tears when you pull a jam out of the printer, spread the paper out and make sure you have all of the pieces. A small shred left inside can cause another jam.

"I also can the drum" - does this mean you discarded the printer cartridge? I've never seen a cartridge cause a jam. Usually an accordion-fold jam in this area is the result of the fuser rollers not turning or a torn fuser sleeve. A jam without an accordion fold indicates that the paper did not make it into the toner deposition area soon enough - this could be a problem with the pickup roller or the next set of rollers. Worn or dirty rollers can work intermittently before they quit completely.

Also, check the paper detection flag to make sure it isn't hanging up (this is a black plastic tab that sticks into the paper path just before the paper goes under the cartridge, and is pushed up or down by the paper). Look for the U-shaped optical detector that is interrupted by this flag, and make sure it isn't blocked by foreign material.

Canon Pixma IP 4300 printer - 3 blinking panel lights indicate paper jam, however no paper jam is present. I turned off machine, pulled power plug, waited for 5 minutes, turned on printer, but problem did...


It is possible that the printer is having an error due to either a sensor fault ( optocoupler) in the paper detect section or a possible software issue.
So disconnecct printter, and uninstall the soft ware , the reinstall and then connecct printer to be detected and installed.
If the fault stays then the sensor must be checked.

Error 6400 ink cartridges wont track accross


The 6A00 is a Canon generic code for paper path jam. Some where in the paper path a sensor is activated indicating paper jam so the printer will give off a 6A00 code. As a Canon tech, I usually find the code, almost 90% of the time, is related to the purge unit being jammed with something and not being able to move. Moving the print head assembly will not clear a purge unit if its jammed with paper, paper clips, push pins, screws, cookie crisp, flower bud pods or the like. And yes I have found all those things in a purge unit. The offending item needs to be removed or the purge unit needs replacement. A Pixma MP830 would still be under Canon warranty, get it into a shop and save yourself the hassel.
Incidently, the 6A00 error pertains to all Canon printers made in the last several years, its not just used in one model. And its always a paper path error or purge unit.
I forget myself so here goes, the purge unit, called a spittoon assembly in an HP, lexmark, and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing. That is why you'll find the print head assembly parked on top of it. It also has a an electrical pump to milk the print heads and test for ink flow.

Two red lights blinking


The flashing red light next to a page and bin indicates paper or a CD/DVD has jammed in the printer.

The flashing red light next to the drop indicates that the ink is low - if it is solid on then the ink is out.

Both of these lights flashing rapidly together means taht the print head carriage is obstructed by jammed paper or some other material and cannot return to the home position. Turn off the printer then open the paper support and the printer cover. Then remove any paper or other obstructions from the paper path by hand / tweezers. Then, turn the printer back on and the fault should clear. If the lights are stioll flashing then check the paper path again and see if the print head carriage assembly is jammed by gently moving it very slightly along the carriage. Don't force this or do this too hard or too far as you can cause some damage to the drive

Follow these steps to clear paper jam

Clearing paper jams
Paper jams can be real or false. The unit may report a paper jam even when there is no jammed paper. The solution to a real paper jam or a false paper jam is the same.
CAUTION:
Jammed paper must be removed using the rear access door with the power cord disconnected to avoid mechanical damage. Do not remove jammed paper from the front of the unit.
  1. Turn off the HP product and turn it around so the back of the unit faces you.
  2. Disconnect the power cord from the back of the all-in-one. The power cord must be disconnected to allow the paper feed rollers to turn freely.
  3. Locate and open the rear access door by pressing in on the left side tab and then pulling the door toward you.
Figure 2: Removing the rear access door

  1. Inspect the pressure rollers on the rear access door and verify that they are clean and turn freely. Clean the rollers if needed with a soft towel lightly moistened with water. If the rollers do not turn freely, replace the rear access door. Click How to Buy on this page to order replacement parts.
  2. From the rear access door opening, remove the jammed paper.
  3. Remove the remaining paper from the paper supply tray. Discard any paper that is damaged or crumpled and then re-stack and reload the paper into the paper supply tray.
  4. Reinstall the rear access door.
  5. Reconnect the power cord to the unit and turn the unit on.
Preventing paper jams
The following information will help prevent paper jams from occurring:
  • Never use paper that is torn or wrinkled.
  • If you are having problems using paper that has already been printed on once (recycling), replace it with new paper.
  • Remove and then reinstall the rear access door. Verify that the access door is fully locked in place. The paper can skew if the rear access door is not locked.
  • Every six months to one year, clean the paper feed rollers with a rag lightly moistened with water. Over time the paper feed rollers accumulate dust and do not function as well as they once did.
  • When printing envelopes, tuck the flap into the envelope and crease the folds before printing.
