Black printing very faint or not at all, cleaning print head makes little difference Brand new Cartridge


Sometimes it will print faint black even if there is a new black cartridge, because the color cartridge needs to be replaced as well.

Make sure that the cartridges are genuine Kodak cartridges, as well, for maximum performance and reliability.

Cleaning heads can use up a lot of ink, by the way.

Printer prints faint labels


Hi. Thanks for your question

Print fainting could be caused by number of reasons. First think to check is ink roll. Replacing with new one would get this out of the way. If it still faints next thing I would do is once you opened the cover try and clean the print head and any visible rollers underneath the labels. Print heads can be cleaned with any alcohol solution. Best would be some kind of electronics cleaning solution. next thing to check would be labels themselves. It happened to me that labels where simply not very well finished and ink would not stick to them. Try roll of labels from other box you may have. If this all failed and your printer still faints labels that it never used to it could be the worse. Your print head may need replacing although this is very unusual for them to fail in this way.
I hope this helped you. Please don't hesitate to come back and ask more questions if this is needed. I've worked with thermal printers for 7 years now and I am sure we can find some solution to your problem.
Thanks for using FixYa

My Epson Stylus CX3810 will no longer print. Tried going through the cleaning head cycle many times and replacing all ink cartridges. only get a faint partial blue line when I print allignment page.


most nearest problem is that ink head not working may be some ink stock inside and no maintenance for that, you need to replace printer head assembly. practically its better to buy a new one.

unplug your printer plug it back in.
open door and take out print ink cartridges.
put them back in and then close the door.

It should now prompt you to do a test alignment page.

Also, Another thing to try is to hit file, top left of page, hit print, click properties. color tab.

make sure you are printing high quality on chose different color management options.

FINALLY TRY THIS:

When Printing Becomes Faint or Colors are Incorrect

the ink tanks, the print head nozzles are probably clogged. Follow the
procedures below to maintain the print head.
Important Before maintaining the print head, check the following;
􀁺 Open the front cover and make sure that the ink tank
contains ink. If it is out of ink, replace it.
􀁺 Ensure that all the orange tape of the ink tank has been
peeled off.
􀁺 Press "PUSH" on the ink tank and ensure that the ink tank
is installed securely.
􀁺 Increase the Print Quality setting in the printer driver
-----------------------------------------------------------------------------------
Printing the Nozzle Check Pattern
Print the nozzle check pattern to determine whether the ink ejects properly from the print
head nozzles, and to verify print head alignment. Use this function when printed results are
blurred or the color is incorrect.

2 Open the Printer Properties dialog box.
See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.
3 Print the Nozzle Check Pattern.
(3) When the confirmation message is displayed, click OK.
When the confirmation message is displayed after the nozzle check pattern has
been printed, click OK.
See "Examining the Nozzle Check Pattern" on page 52.

itself. With the printer on, load a sheet of Letter-sized paper in the
printer. Hold the RESUME/CANCEL button until the POWER lamp flashes
--------------------------------------------------------------------------------------

See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.

Canon IP 90 clogged printhead nozzles. How to remove printhead?


Hi there,

To avoid drying of the Print Head and clogging of the nozzles, note the following.
*When you turn off the Machine
Follow the procedure below to turn off the machine.
1)Press the ON/OFF button to turn off the machine,
2) Confirm that the POWER lamp has gone out.
This takes a few seconds or as long as 20 seconds.
3) Unplug the power cord from the wall outlet.
If you are using a power outlet strip, you can switch off instead.
When you press the ON/OFF button to turn off the machine, the machine automatically puts a protective cap on the Print Head to prevent the ink from drying. If you remove the power cord or switch off the power outlet strip before the POWER lamp goes out, this capping will not be done properly, causing the Print Head to dry and clog.

* When You are not Using the Machine for a Long Time.
When you are not using the machine for a long time, print or copy in both black and white and in color or pertorm Print Head Cleaning, about once a month to prevent degradation of the Print Head.
Numerous nozzles are installed in the Print Head for high -precision printing. Just as the uncapped tip of a ballpoint pen or marker becomes dry and unusable if it is not used for a long period of time, the print nozzles becomes blocked by dried ink. Periodically printing or cleaning of the Print Head can prevent this blockage.
Note :
*If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat, ink may blur depending in the paper.
*If the print head nozzles get clogged , printouts will become faint or particular colors will not be printed properly.

The PHOTO mode is for printing grayscale photographs. Printed letters using PHOTO mode may appear faint because PHOTO mode is optimized for halftones. See if there is a TEXT or LETTER print mode, and try printing on that setting. If printed letters are still faint, you may have to go into ADVANCED PRINTER PREFERENCES, and see if the TONER SAVE mode is on. If it is, turn TONER SAVE off. Also, try changing the DPI image density, or try other adjustments in the ADVANCED PRINTER PREFERENCES MODE.
