Step followed:-
1. Remove cartridges.
2. Press and hold the Power Button and remove the Power Cord from the back of the Printer(in printer ON state).
3.Shake the cartridges and clean the cartridges.
4.Clean the printhead softly from cotton clothe.
5.Put the cartridges again.
6. Press the power button and connect the power cord.
7. Clean and allign catridges from printer control pannel.
This might can help you and try to put some thick paper instead of normal paper.

Hey,

Remove the cart ridges, restart printer, does the lights still flash? restart printer, place cartridges back in, make sure the tape is removed from the cartridge. also you can try cleaning the contacts.

So after you have connected the carts again, restart printer. how is it?

Thanks,
Ekse

cartridge blinking

Get the new ink, when the ink light begins to flash, that will be the time to change it. Press the ink/cleaning button, the printhead will advance to the left, open the cartridge door, replace ink, close the catridge door, and hit the button again.

thanks adi

Take out the power cable from the back of the printer keep on tapping the power button for 30 secs ; then plug it back.
Take out the catridges clean them with a Lint free cloth (copper contacts); also clean the catridge slot of the printer; put in back the catridges ;
Unplug the power cable from the back of the printer; press and hol down the (#) and the (6) button simultaneously with one hand and with the other hand put in back the power cable; and then release the (#) and (6) button;
It will perform a reset on the printer
IF still then it doesn't work then the catridge slot's copper contacts has gone bad and need to replace

This is a problem, sorry to say. The Mark Encoder is not being detected. In laymans terms this means that you need a new carrage. Part Number is C4713-60039. You also need to check on the condition of your belt at the same time. Is there somebody in your area that can do the work or are you capable ?

some problems with compatible cartridges can be solved by taking all the ink out and powering the printer off then back on then put the ink back in, you might have to do this a few times also make sure no ink or dust has built up on the pins.

Ok please try




1. Turn off printer
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not, press the Power button once more.
8. Your printer should respond as normal.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Hello there... you probably have a damaged trailing cable!!!

Some problem in Catridges, take the white petrol and clean the head of the catridge and try again.
