Unseating and reseating the cartridge
Turn the unit on and open the lid or top cover.
Remove the cartridges.
Re-insert the cartridges.
Close the unit’s lid or top cover.
Cycle the power to the device by turning the printer off for a few seconds.
Turn the printer back on.
Print a test page. If this does not solve the problem, proceed to the next section.
Wiping the cartridge contacts
Turn the unit on and open the lid or top cover.
Remove the cartridges.
Using a clean, dry lint-free cloth (a coffee filter works well), wipe the cartridge contacts, from the top to the bottom (see Figure 1). The contact area of the cartridge should be rubbed briskly to remove the waxy lubricant material from the gold contacts.

Cleaning the Service Station.
1. Remove the service station motor by removing one screw.
2. Scrap as much congealed ink as possible from the service station.
3. Soak the service station in hot water to dissolve the remaining ink. This will take a while but after a few rinsings nearly all of the ink will be removed.

Hope that helps..........

Printer acts like it is printing and there is ink in the printer but pages are coming out blank


The ink-jets that SHOULD be spraying the ink onto the paper are clogged.

Run a few "print-head-cleaning" cycles, to try to unclog the ink-jets.

My printer ink is full and it just printing in black and yellow


The ink leaves the ink-cartridge, and should flow through the ink-jets to be sprayed onto the paper.
If some of the ink-jets are clogged (blue, red) and some of the ink-jets are fine (black, yellow),
then you need to run a few "print-head-cleaning" cycles, to try to unclog those ink-jets.

Almost every 4 lines the ink is very faint


The print-head is like a paint-brush -- it paints many "rows" in one swipe across the page.
So, some of the ink-jets in the print-head are clogged.

Run a few print-head-cleaning cycles to try to unclog all the ink-jets.

Why is there a clear horizontal line within the printed line?


The print-head is like a paint-brush, in that it prints a "band" as it goes across the page.

In your case, some of the ink-jets are CLOGGED, and thus are not shooting ink as the print-head moves HORIZONTALLY across the page.

Run a few "print-head-cleaning-cycles", to try to unclog those ink-jets.

My printer is printing photos and they are blue. Am I almost out of ink?


You either are out-of-ink, or the ink-jets are clogged. Run a "print-head-cleaning" cycle to unclog any jets.

Color ink cartridge show a full ink supply, but it won't print color.


It's possible that the ink-jets that spray the colour ink onto the paper have become clogged. Run the printer software, and select a "print-head-cleaning-cycle", to try to unclog those jets.

Won't print...says it is printing but doesn't


If you have lots of flashing error lights or electrical problems then it is likely to be electrical.

However, if like most... and your
printer has just been left unused for some time? You probably just have an ink clog.

Provided it worked OK before a period of non-use? Then you just need to use a PRINT HEAD CLEANING KIT to unclog the tiny jets.
Magic Inkjet Flush usually works a treat on those!

Magic is ideal for unclogging the tiny jets on any Canon,Epson HP and removing those horrible white lines which usually appear in prints whendried ink clogs several jets...

So if yours appears to be a clog? all you should need to do is to use the MagicInkjet Flush kit to soak the print head and you should be printing again like new.

How can you clean the printer but clicking on


Hi
If yourPSC 1210v printer has been left unused for some time? You probably have an ink clog and the standard cleaning is not enough to clear the clogged ink.

Assuming your HP 56 57 still has ink? Empty they are about 30g Each 1g over that is 1ml of unused ink.

Provided it worked OK before a period of non-use? Then you just need to use a PRINT HEAD CLEANING KIT to unclog the tiny jets.

I put a new color cart in and now my pictures have a green hue to them


Hi
Sounds like too much cyan.
Remove ink and place onto a paper towel.
If it appears too much cyan *blue then let it stand for 2 mins. You can do the same if mixed.

Once normal colours appear try again.

However, if like most... and your printer has just been left unused for some time? You probably have an ink clog on the cyan and magenta.

Provided it worked OK before a period of non-use? Then you just need to use a PRINT HEAD CLEANING KIT to unclog the tiny jets.
