When printing from a computer, the printed document or image may appear to have a coloured cast that is not shown on the original image. The sample images below are examples of colour casting.
|Original||Cyan cast||Magenta cast|
If you are having print quality problems, follow the steps below to investigate the possible cause of a colour cast on your printed image(s) and how to troubleshoot the issue.
Colour casting can be caused by blocked nozzles on the print head, you may be able to identify the problem by checking the print head nozzles. if any colours are missing you can check the print head nozzles from your computer by using the Nozzle Check utility.
Performing a nozzle check will determine if any of the nozzles are blocked.
Make sure that you are using genuine Epson ink cartridges before completing any of the below steps (see Why should I use genuine Epson ink cartridges?).
For detailed instructions on this step see How to open the Devices and Printers folder in Windows.

Good nozzle check sample
(print head does not need cleaning)
|Poor nozzle check sample (print head needs to be cleaned)|
If there are no print quality problems, such as gaps or missing segments in the test lines, the print head is fine. Move to the next step.
If there are breaks in the printed pattern, such as missing segments or lines/streaks (depending on the type of nozzle check pattern), or a missing colour, this indicates that the issue is related to the print head, e.g. a clogged ink nozzle or a misaligned print head. and/or ink cartridge (e.g. old cartridge, non-genuine Epson or refilled ink cartridge). If a colour is not printing at all, there will be a colour imbalance that will cause a 'colour cast' effect.
The solution is to run through a series of head cleans. Refer to one of the following articles for further assistance:
Avoid using old or damaged ink cartridges. If the cartridges have been installed in the printer for longer than 6 months then you may see a decrease in print quality over time.
We recommend you use up ink cartridge within six months of opening the vacuum package and before the best before date shown on its retail packaging. Replace any old or damaged ink cartridges with new, genuine Epson cartridges for best printing results.
If a cartridge has been installed in the printer for longer than 6 months, then over time the ink from the cartridge may start to dry out and cause ink to become clogged in the printer. You may see a decrease in print quality if any nozzles on the print head are clogged with ink. This can result in missing colours, which in turn results in a colour cast.
When printing photographs using the correct media is essential. To ensure you get the best quality from your Epson printer we recommend you use only paper supported by Epson. Epson offers specially-designed paper and other print media for all your printing needs.
Use only one of the recommended Epson paper types with your printer. To ensure you get the best quality from your Epson printer, you should use genuine Epson ink and media. Some non-genuine Epson papers are made for inkjet printers which heat the ink before transferring it to the page, thus the paper coating is manufactured to bond with this hot ink and fuse it to the page, potentially resulting in poor print quality and colour casts.
The end results from third-party media are often not favourable when compared with prints made on genuine Epson papers. Epson printers are very carefully tuned to ensure Epson inks and Epson's Micro Piezo print head produce the best quality prints using carefully selected Epson paper. See your printer's user guide for a list of suitable Epson paper.
Epson recommends the use of genuine Epson ink cartridges. Epson cannot guarantee the quality or reliability of non-genuine ink. The use of non-genuine ink may cause damage that is not covered by Epson’s warranties, and under certain circumstances, may cause erratic printer behaviour. Information about non-genuine ink levels may not be displayed, and use of non-genuine ink is recorded for possible use in service support.
A colour cast can also be software related. Before printing you will be given the option to go into the Printer Properties or Printing Preferences in Windows or Print Settings in Mac OS X.
From here you can alter settings which control the printer. Make sure the correct settings are in effect for the type of print you are sending to the printer e.g. the paper type and quality.
|Windows||Mac OS X|
To print in black you will need to select the 'Black Ink Only', 'Grayscale' or 'Black' print mode option in your printer driver. See Related Article How do I select the 'Black Ink Only' or 'Grayscale' print mode? for assistance.
