Only insert the failing printheads, all others being removed, one by one, and check if they are being rejected outright. Sometimes faulty printheads cause other printheads to be rejected so your problem could be actually with one of the other PHs. Faulty PHs can cause a lot of funky symptoms in the carriage assy and while disuse kills any inkjet, there are no ink components in the carriage assy (the tubes are seperate) so disuse damage to the carriage is unlikely. The Phs and the tubes though, thats another issue entirely. A tech that cannot spot a heavily used Printer is no good. It takes a good tech one look at the S/N, the service station and the belt to tell you how well used a printer is. Most of the small DNJs see very little use anyway. Also a lot of you are referring to some endemic "yellow issue". After talking to a lot of ex-colleauges who serviced a few hundreds in between them, no one could confirm a distintive yellow issue, the only thing was that the thin lines of the 130 are more prone to air bubbles/drying in, and this kills PHs in short succession since you only print out of the PH reservoir when your line is clogged. Since yellow is usually used the most, clogged lines show up earlier here than they do with other colours. I also suspect yellow "gasses out" more than other colours, but this is pure suspecion. The early symptoms of clogged lines/empty heads are bandings which show up during the print and then (sometimes) vanish at the beginning of the next print, only to show up again during the print, with the time before the nozzle outtage gradually decreasing. Far from unfixable you can easily repair this by manually purging the tubes. Instead of using the button commando for a purge (whiyh only works if the PHs and cartridges are are completely air free, (read: new or recently inserted and the Phs were never used for purging) just remove all PHs, all inks, disconnect the Printer from the power grid and carefully insert an empty syringe without the plunger into the ink valve of the affected PH slot. This is needed to open the rubber valve and catch excesss ink. No take the cartridge, carefully cut the lables at the lower gap in the plastic (or remove the labels) and remove the cartridge bottom to expose the rubber bongo. There is no need to remove the whole ink sack from the cartridge, but you can for easier access for what comes next. "Insert" the cartridge into the printer while exerting pressure on the bongo with your pinky finger, as soon as the male connector from the slot enters the female connector on the cartrdge you'll feel the bongo drepressing and should already see some ink bubling into the syringe. Manually "pump" with your pinky while keeping the cartridge down to keep the valve open until no more air is visible in the tube affected and the ink flowing out into the syringe is bubble fee. Now the hardest part, remove the syringe while closing it off with the piston or your thump, have paper some ink receptacle and paper towels handy. Do not try this in your sunday dress :-) Repeat as neccessary and replace the failed PH, There is no practical way of refilling an empty PH reservoir as the air inside is trapped by a valve and cannot escape through the nozzles either. I know it hurts, but if there is too much air in the cartridge pumping mechanism visible, throw that one out as well. If you regularly check the lines for excessive air bubbles, esp. after streches of disuse, you can perform this procedure preemtively before your Ph sucks in too much air. Don't get paranoid though a few % of air in the tubes don't hurt. ***disclaimer*** This procedure voids the warrenty of your cartridge, and your printer. The syringe can damage the valve if you push it ink to deeply, spilled ink can fry both the cartridge station and the carriage, so don't do that. Do not try to "suck" the ink into the tubes with the syringe, this only works on larger designjets with pressurized cartridges without the pumping mechanism. The procedure described above should work on all DNJs based on the 100 series chassis, the 500/800 series the T series, the Z2100/Z3100/Z3200/Z5200 series and the odd business inkjet.
