Remove cartridges and blow on the gold contacts on them. do not touch the contacts this is your print head. When you cleaned them if you used liquid on them then they are ruined. Re-install them, if you still get this message replace the one with the flashing light. My canon has a flashing light in the cartridge that will tell you which one to replace, yours should have the same.

Hi. Most ink cartridges are cyan magenta yellow and black. You do have to have all cartridge installed for it to work. If it's been sitting for a while ink dries and can cause all kinds of little problems. The ink cartridges have little contacts on them you might have to clean these with a cotton swab and alcohol. But if the ink has dried in the print head you have to clean all the little ink ports on the head.

My printer will not print black ! it prints every other colour, but not black. I changed the ink cartridge and i cleaned the heads. What else can i do? It has been a loyal printer until today. please


Hi you mentioned that the Ink is new and that you have cleaned the ink heads, have you checked if the silicon Film for the ink cartridge contact was removed?

if that film is not removed cleaning the printer head will still not detect the ink cartridge for the Black on your printer.

Turn your printer OFF and remove all your print cartridges then install all of them again one at a time then turn the printer back ON, see if all the ink cartridges are now detected and if the Black will now print.

Also if you can

Have error message UO52 print head is incorrect, have installed correct ink cartridges what do I do ?


Hello,


It could in fact be a defective print head problem but try cleaning it first:

(1) Open the printer
(2) Remove the ink cartridges from the print head.
(3) Use cotton swabs dipped in hot water to thoroughly clean the print head.
(4) Repeat this until there is no ink residue coming off on the cotton swab.
(5) Once finished, allow to dry and replace the cartridges
(6) Try to print something now

I have an error "unable to print 36" on my


If caused by a paper jam you had it probably lifted the long, thin, plastic encoder strip in the pathway out of its slot, giving the false indication of a paper jam. In order to put it back in its place, please carry out the following steps:

1) Lift the cover and remove the two plastic panels covering wires. Mark down the position of cables, then remove them, and remove the now-freed top scanner section entirely.

2) Remove the screws from the top plastic shell. There's two in the back and four in the front. There's also two plastic tabs in the front that must be bent aside before you can remove the top shell.

3) Gently put the encoder strip back in its plastic guide, and check if you are able to get your printer to work all right thereafter.

If you are not comfortable carrying out the steps, I would strongly suggest you to have it repaired by your local Brother service center, without causing further complications.

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.

My canon MP810 all-in-one printer, i've cleaned the printer head, and i have replaced the ink cartriges with new Canon brand, but till got error code U052


Printing with an empty ink cartridge may cause printer malfunction. U051 / U052
U053 / U059 The ink cartridge may not be set properly, or an ink cartridge not supported by the printer is installed.
Install the proper ink cartridge.
If one of the ink cartridges is missing, this error will occur. U075 / U076 The ink cartridges are not installed in the proper position. Install each ink cartridge in the proper position. U140 An ink cartridge not supported by the printer is installed.
Install the proper ink cartridge. U161 / U162 A used ink cartridge may be installed, or the ink cartridge may be empty.
Replace the ink cartridge.
By pressing the OK button, printing can be done without replacing the ink cartridge. However, the remaining ink amount cannot be detected properly, so the function to detect the remaining ink amount does not operate. READ/WRITE MODE Since the memory card is currently write-enabled, printing is not possible.
Set READ-ONLY MODE ON. NO PHOTOS ON CARD Some images in the memory card may not be in a supported format. images listed below cannot be printed directly from a memory card. Print them from a computer.
The waste ink absorber is a part inside the printer, which absorbs ink used in the cleaning operations, etc. CHECK PRINTER Turn the printer off, and remove the power plug from the outlet.
About ten minutes later, plug it in again, and turn the printer on.
If the problem is not resolved, the printer may require servicing. Please contact your local Service Center.

I have installed a new pg 30 print cartrige in my Canon MP 470 printer and I get a U051 Error print Head is not installed error. How do I reset printer to fix this error?


Hi there !

The ink cartridge is not properly fitted or installed or does not detect the ink catridge, remove again and fitted it correctly.
.
Also, clean with alcohol the gold chips of the ink cartridge and maybe there is sticky residue when you remove the sticker. Turnoff your printer and plug it on again to refresh the memory.

I hope it helps you.

Brother lc61 printer will not print in black even wit a new cartridge installed


Hi innercepter,

1) Open the printer
(2) Remove the ink cartridges from the print head.
(3) Use cotton swabs dipped in hot water to thoroughly clean the print head and each ink cartridge.
(4) Repeat this until there is no ink residue coming off on the cotton swab.
(5) Once finished, allow to dry and replace the cartridges
(6) Try to print something now

If that does not work then you have one of two possibilities:
(1) One of the ink cartridges is defective and causing the error
(2) If it's definitely not that, then the print head will need to be replaced.
