Dear experts, i have used syringe type refill black ink for quite a long time
without problem. but presently i carelessly refilled and used that cartridge in rush before i used to left it overnight after refill. the result is left over images. so at maintenance menu i tried to clean for about four times normally without improvement, then i tried deep clean nozzle. after that there is no image at all. replacing the head with known good one also no image. i read fixya forums and carefully and gently dismantled waste ink pad, cleaned , put it
back neatly but still no image. the printer shows no error blinking and print normally without image. original head also dipped in solvent and cleaned but same fault. does the pc board faulty? pls help.
Henry can you try a new cartridge in the printer. Maybe borrow one from a friend?
Printer cartridges are very delicate and hold most of the technology to do the printing.
It sounds to me that you need to replace the cartridge.
They are not meant to be re-used lots of times. Although you can prolong there life (And save your cash) re-useing them
I am sure you are aware that the manufacturer recomends only thier cartridges and us once buy new. Maybe you have saved all the money you can on this one.
Let me know how you get on please.
