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.

Error message print unable 50

the encoder strip which gives the printhead the position is out of place (error 50). You have to open the printer and reinsert the strip:

Stick a 1.5 inch tape onto the printhead cover where the strip runs thru. This will prevent this accident in future!
