Windowlene's one of the substances I'd generally avoid putting through a printer as it can cause contamination issues... The American 'windex' product is what is widely touted as a cleaner for Epson printers... From the Wikipedia entry on Windex...
"The Sam Wise patent #3,463,735 lists several example formulae, one of which is 4.0% isopropyl alcohol (a highly volatile solvent) 1% ethylene glycol monobutyl ether (a less volatile solvent), 0.1% sodium lauryl sulfate (a surfactant), 0.01% tetrasodium pyrophosphate (a water softener), 0.05% of 28% ammonia, 1% of a dye solution, and 0.01% perfume."
...Your printer can probably really do without the perfume, surfactant, water softener, dye and perfume; all potential contaminents! And the trouble with the Windowlene is that people (half understading what they're doing) WILL try this trick using the pink creme stuff (as opposed to the liquid) - and cause all sorts of issues in the process!
...If you MUST use Windowlene it needs to be the CLEAR liquid type ONLY!
However; there's a cheaper and better solution...
It's the IPA (isopropyl alcohol) in Windex/Windowlene that does much of the work... You'll find this is a VERY good solvent for most ink. It's also volatile enough to evaporate completely and leaves no deposits behind. - Used regularly in science and industry on all sorts of sensitive optical and electronics surfaces that need to be left perfectly, chemically, clean...
Ammonia is also a key solvent for many inks... Though you shouldn't use it neat. A mix of 10% Ammonia to 90% IPA is often used by print technician
IPA can be obtained from various suppliers - By the gallon off Ebay if you so desire. The purer it is the better IMHO. Some people though DO dilute it with distilled water - which would be fine if you're using water-based inks...
We've revived printers that were left for dead literally YEARS ago using IPA and techniques very similar to those posted above.

A GALLON of the stuff is £18!
