EPSON - MISSING COLORS FOLLOWING REPEATED “HEAD CLEANING”

Regarding your recent inquiry about the T127 cartridges poor print quality (lack of yellow printing), be

advised that Epson printer systems are notorious for getting dried ink nozzles and/or dried PRINTHEAD

ink ports. Often the ink cartridge only has to be uninstalled for less than 8 hours and dried ink (ink

starvation) issues can easily occur. You indicated that you already recovered the black ink by performing

the 'head cleaning' twice, this is a sure sign that the PRINTHEAD has suffered prolonged drying and is the

likely culprit which is still causing the yellow ink starvation.

Please perform the following steps - A. thru C:

A. At the printer’s control panel under the ‘Maintenance’ or ‘Tools’ menu, activate the ‘HEAD CLEANING’

2-3 times to fully re-prime the ink system until the Yellow recovers. Retest by printing a self-test page to

verify all colors are firing properly. We also provide a more intense ‘Ink Recovery Test Print’ on our

Inkjet411 Test Prints page: http://inkjet411.com/?page_id=146

> If all colors do not recover then proceed to Step B.

B. If this does not remedy the yellow starvation issue, then the yellow ink port may be partially dry

within the PRINTHEAD assembly (the ink cartridges physically connect to this electronic assembly). We

suggest you 'wet' the PRINTHEAD INK PORT. Using an eye-dropper, or similar, drip ~5-6 milliliters (or

approx. 1 teaspoon) of distilled water into the respective YELLOW ink port. Re-install ink cartridge and

perform a 'Head Cleaning' to flush the water out & re-prime yellow ink line. Refer to video on how the

PRINTHEAD functions: http://inkjet411.com/?page_id=2054

C. If the PRINHEAD cleaning is successful, but ink levels are severely low, you have the option of

returning to Costco and request to get all your ink tanks (CMYK) refilled, at no charge. Following the

PRINTHEAD cleaning you will lose a significant amount of ink (typically ~8% per cleaning action or when

the PRINTHEAD is removed in reinstalled). Just tell them an Inkjet411 representative sent you with this

support request. If you have any troubles with such a request, we will contact the regional account

manager whom will contact the store directly for free-refill authorization.

NOTE: Cartridges will be rejected for refilling if each cartridge ink level is not below 25%.

PRINHEAD TECHNICAL NOTES:

The Epson IIT (individual ink tank-based) printer models have an electronic PRINTHEAD within the base

of the carriage assembly (responsible for pulling ink from the 4-6 ink cartridges and then firing the ink
