How do I make a test page for my printer to check color.


You need to clarify :
1. Your printer cannot print color even though it prints color well from a test page;
2. Your printer cannot print color in a test print page.

If it is the first one, then you have to set it properly in Window Print Configuration page of that printer;
If it is the second one, then you have to check whether you have installed the color ink cartridge properly in the printer. If the color ink cartridge is installed properly, try to replace another new color ink cartridge. Finally it is still not work, then you have to bring back to the repair center.

I have a Lexmark Pinnacle Pro 901 printer and its set up to print using black ink only, but it keeps telling to replace color cartridges and it won't let me print at all, how do I print using blac


The printer would need all cartridges to have sufficient ink levels to continue printing - that's to prevent damaging the printhead. Every time a cartridge is replaced, all colors are primed simultaneously thus the need for all cartridges to have ink.


To save on your ink investment, try printing in draft mode and by making sure that your printing preferences is set to print using black ink only.

Ink shows full but color won't print


Uncommon faults are with the electronic drivers in the printer system that drive and control the printer cartridges. This is providing the cartridges are proven to not be defective. Also, jammed nozzles will prevent printing.

Make sure your software is not set to print in monochrome (B&W) only .

I have changed the colour ink on my canon mp460 but it still say empty


CL41, this is the one you are using for your cartridge.

Did you change your cartridge with brand new one or refilled one??

If you did with refilled one, the ink level won't go back with full.

-------------------------------------------------------------------------------
This is the method how printer measures the ink level.

1. Each cartridge has a serial number.
2. As soon as installation in printer, printer recognizes the cartridge by serial #.
3. And the printer starts to count the printing document.
4. After reaching certain print counting, the ink level will show "low ink"

So my answer is even if you refilled your cartridge, the ink level won't change,
since printer cannot weight the cartridge or.....some other technology to measure each color ink level.

Thanks.

My Lc61 will not print black--on the test page, the colors are fine. I've replaced the ink cartridge and it says it's full but won't print


Most likely this is a print head issue. The print head is what the cartridges sit in inside of the printer. To attempt to resolve it, do the following:

(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.

Bland and color cartridges have been refilled but


Ink level counter (program) didn't read actually ink at ink tank. Brand new cartridge ink level counter 100% (full), and ink 100% (about 10 ml). After may printing, ink will dry out, and ink level counter reach zero (ink out). Printer will not allow print anymore, even have refilled, because ink level read "ink out". For canon type, you just to release ink level counter, and counter just stop, but printer will allow to print. Press stop/reset button for about 30 second.

After installing re-filled ink cartridges, both color and back & white, the printer message that shows ink level still shows low level ink? How do we resolve?


Hello,

Try this procedure:
1. Open printer lid so cartridges move to center of carriage.
2. Lift clamp and remove black or color cartridge from the holder.
3. Place cartridge on table with copper contact strip facing you.
4. Carefully place a strip of clear plastic tape over the four contacts on the upper left corner of the cartridge.
5. Reinstall cartridge in printer and close lid. Wait until cartridge returns to parking position.
6. Open lid and remove cartridge again. Remove tape from left side and place tape over four contacts at upper right corner of cartridge.
7. Reinstall cartridge in printer and close lid. Wait until cartridge returns to parking position again.
8. Open lid again, remove cartridge, remove tape.
9. Reinstall cartridge and close lid.
Printer will now recalibrate. Once the process is complete the ink level meter should be reading full again.

I hope this helps, if so please rate our solution.

HP 932 RED LIGHT STAYS ON


The light you describe is the ink light.
When that light is blinking, try this.

Turn on the printer. Open the front cover and look at the carrier for the ink cartridges. There is a white arrow right above the latch for the color cartridge.
Once the carrier stops moving, the white arrow should be pointing to a symbol which represents the problem (the reason the light is blinking.) Examples are low ink black, low ink color, sick black ( replace ) , sick color ( replace ).

IF you have just replaced your black cartridge, you might need to replace your color cartridge too.
This printer will not work without both ink cartridges installed and full.
You cant print with a full black and an empty color cartridge unfortunately, even if you only want to print black.

Hope this helps!
