HP Deskjet 640C doesn't print after being long out of use. Cartridges are empty or dry. Is there a way of replacing only the black cartridge for B/W printing by "cheating" the printer? Thx Robert

I found perhaps a couple of cheats when it comes to desktop printers. Their is a RESET BUTTON on the cartage itself that will give you more ink out of your cartage.

I have 640 c printer

the refilled cartridge probably has expired (yes. hp cartridge got expiry dates!!)

exchange the ink where you got it from. and ask for a 'fresher' one

but my advice is to change the printer. this model uses 3-in-1 inks that is not economy. get one with all seperate ink tanks.

My printer do not print any file

I usually face the following problem while giving printing command to my printer:\r\n
1. On clicking print from file meno the printer does not print and the yellow light upwards starts blinking.
2. Reinstalled the printer after inserted the Printer Software *C6464-10018* v 41 *MacOS 8.1*USB
but printing did not start from this even.
3. sometimes earlier I experienced that only 2-3 lines get printed and after that the upper yellow light again started blinking.
4.Some times the printer goes on sucking papers and prints as the signs of playing cards or some other abnormal shapes lining etc.
Please be kind enough to solve my all such problem and if possible point out step by step action to be taken by me during such an eventuality at a later stage also.
