Unable to Print

For days now, every time I try to print, I get an error 5700 message. I have no idea what this means...can someone please help me? I tried to check for a paper jam, something with the ink jets perhaps, connections and shut down and back on again and it is the same problem.

Re: Unable to Print

You need a new sheet feeder unit (QM2-2211). The machine has to go to a Canon dealer as they are a cow to fix

Re: Unable to Print

Maybe if you rubbed some cheese on the front, that would work? Hope this helps.

Error message reads "unable to

It means that the printer is unable to clean the print head number(s) 46. The print head is located under the ink cartridges. Remove the cartridges, and you should see a plastic piece with a hole in it to put your finger under and snap open. This allows you to see the print heads. The print heads look like a sponge type dabber on top of a plastic case. Grab a hold of the print head and pull it out. Look for ink that has spilled behind it or on any of the brass colored computer connections. use warm water and a lint free cloth to scrub it off. Press the print head sponge with your finger and make sure that ink primes and fills the head then put the printer back together and try a test page. If you stll get the error then you need to contact brother for a print head replacement.

Hi I have Brother dcp 350 printer. I have the error 46 unable to print/clean i cant get the printer back to normal functions. I have change the inks (all) and I am still get the same error message 46....

The messages unable to print, unable to clean, unable 36, error 46 and error 32 are all print head errors.

1. Remove all the ink cartridges from the machine
2. Clean the contacts on the cartridges as well as inside the machine itself with a small amount of warm water or alcohol on a cotton swab until no ink comes off on the swab.

Note: if any of the other cartridges are low, empty, leaking or bulging replace them

3. Then turn off the machine and unplug it for 70 seconds
4. Plug it back it and wait for the insert cartridges message
5. Insert the cartridges and check to see if the problem is still there. If it is it means the print head has failed and in order to fix this the print head inside the printer needs to be replaced. The print head is the part of the printer that puts ink from the cartridges onto the page

Unfortunately this can sometimes cost more to replace then the machine itself.

Printer message "unable to print 36"

That error usually means a paper scrap or something is stopping the carriage from moving across the paper correctly, or there are scraps caught on either side of the carriage assembly.

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.

Printer message: Unable to Print

5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!
