Re: Printin

I don't know exactly what I did but I felt around for the foil and pressed it against the printer head and kept my fingers crossed.  Then the printer went through the cleaning process and, lo and behold, I now have a printed sheet of paper.  Brother's website and owner's manual have NO trouble shooting guide worth using!
Thnaks for the fix!

Re: Printin

With my printer, model mfc 665cw, it's really hard to access the encoder strip because it's blocked. I managed to find it by gently running my fingers where the paper jam had occurred and I found it. I applied alittle pressure all the way across the strip to move it down in place. The printer went into a cleaning mode and began to work properly again. Thanks (mix-it-up) for the heads up that that was the problem.

Re: Printin

The CR encoder strip is not in position. Its the encoder strip which gives the printhead the position. It runs upon the printhead (a small foil strip). BTW this happens quite often because the jammed paper lifts the strip out of position. You ve to open the printer and simply put the encoder strip right into its rail between the senor upon the printhead again.

While printing 2 or 3 lines it shows paper jam message. Can't print even a page!!!

make sure you don't have any small pieces of paper stuck in the printer s.gif s.gif s.gif
Paper jams can be real or false. The unit may report a paper jam when there is not any jammed paper, however, the solution to a real paper jam or a false paper jam is the same. WARNING: Jammed paper must be removed using the rear access door and the power cord must be disconnected or a carriage jam or mechanical damage may occur. Do not remove jammed paper from the front of the unit.
  1. Turn off the HP product and turn it 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 1: Removing the rear access door c00108288.jpg 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.
  4. 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.
  5. From the rear access door opening, remove the jammed paper.
  6. 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.
  7. Reinstall the rear access door.
  8. Reconnect the power cord to the unit and turn the unit on. If a carriage stall occurs after clearing the paper jam, resolve the carriage stall.

Unable to print or copy, see troubleshooting 51

The error means you have a paper jam or one of the sensors is incorrectly reading a paper jam. Unplug the unit and check all areas for a jam. Remove the back Jam Clear Cover and check inside there. Remove the Paper Tray and check that area and check if the PE actuator is in place behind the paper tray. Lift the scanner flatbed unit and check inside the print carriage area. Look for scraps of paper at the sides of the platen. These scraps that may be soaked with ink and difficult to see. You may need to move the print head to see both sides.

If the PE actuator is missing, contact Brother for a replacement. Put in the replacement if needed.

Close the scanner unit, replace the clear jam cover (put it on correctly) and replace the paper tray. Plug in and turn on the printer and see if the message clears. If it doesn't clear, access the Ink or Ink Management menu (either directly by a single key or through the menus). Do a test print for Print Quality (Color). If the quality is good, press 1, the up arrow or + key to select Yes. Then press the Stop/Exit button. If the print quality is poor, clean the print head.

If the jam message occurs again, check for more scraps of paper inside the unit as above. Make sure your paper meets the specifications for the printer and isn't getting excessively humid. (Paper will pick up moisture from the atmosphere so keep only the needed amount in open reams or the paper tray.) Fan the paper in the tray and then return it to the paper tray. Make sure the paper is flat in the tray and that the guides are just touching the edge of the paper.

If it still doesn't clear, the unit needs service.

I hope this helps.

I'm getting an error saying Unable to print 30

  1. Clean all feed wheels and guides with methylated spirits.
  2. Look for any switch or guide that may be bent or out of place. This could have been damaged when a jam was removed.
  3. Look for any small piece of paper or staple that may have lodged in the paper path somewhere.
  4. Ensure the paper is dry. Not stored in a cupboard in the kitchen or the printer is not setup infront of an air vent.

My Epson LQ-590/LQ-2090 keeps having paper jams located just beyond the tractor feed.. help

When a paper jam occurs during printing for some reason, the printer beeps, displaying the message <PAPER JAM> in the display. When a paper jam occurs, remove the jammed paper using the following procedure, and then resume the job. If the message that indicates the paper jam does not disappear even after removing the jammed paper following the procedure, there is a possibility that torn pieces of paper are still left inside the printer. Inspect each part of the printer again, and completely remove all pieces of jammed paper.

Paper jam. caused error print unable 30

"Machine Error 30" (or "Unable to Print") indicates either a simple problem such as a paper or part of a paper stuck inside the machine, which of course is solved by opening the machine as much as possible and remove the reason for the jam.
Even a ripped part of a paper will be able to cause the paper, so it's important to be careful when taking jammed paper out to not rip the paper (do this by carefully pulling the paper among the same way as it would go when printing, not the opposite direction).

However, if that doesn't work, the error is mechanical (but still most likely caused by the jam, either a sensor getting dirty and unable to do it's work, or actually getting broken), and there isn't much you can do. If the message comes back right after turning on the machine, you'll have to have service performed on the machine.

Message unable to print 50

Machine Error 50 either means that there is a loose object inside the machine (usually piece of paper), or that there is a mechanical error which would need you to have the machine sent to service.
