I have a Roland Versacamm

hold down the on/reset button a few seconds ....on some printers this will reset it and it might just work ...

I have read through the comments you have posted. If the lines are not blocked and the nozzle is not clogged then you have to have either a program fault or a hardware fault. Double check your contacts on the cartridge to make sure they are making contact. If possible clean the contacts on the printer, you should be able to carefully use an eraser to clean them. If these are clean try printing from another program to see if the printer will print Yellow. If the other program works then you need to re-install the program you have having problems with. It may be a good Idea to remove and re-install the printer drivers to the computer as well. Hope this helps.

Unfortunately it sounds like the wide format printer you have will need some hardware replacement, it sounds like some part of the ink control has malfunctioned =(. Very difficult to say what you have going on, you sadly will have to call Roland to have them diagnose it. Their number is:

Hello, regarding on your problem i suggest that if you can find a computer shop in your place or contact the supplier of your printer then let them examine and fix the problem. In that way you are assured that they can fix it because they have complete tools and equipment for repairing and fixing the printer's problem. Also to prevent any additional damage from your printer cause if the ink continues in dropping out the yellow ink it might possibly damage the printer board and eventually you have to buy new one. So the best and simple suggestion please follow the instructions above.

Thanks

Re-clean. There may be a nozzle clogged.
Use Isopropyl alcohol and a cotton swab.
Also clean the contacts with an eraser - run test pages to verify proper ink usage.

Thanks

I am not a printer expert but I believe this printer has a pump and ink supply lines? Is it possible that either the supply or the drain lines may have a plug? I would disconnect the lines and check them for stoppage, then reconnect and check the dampers, supply, drain lines and dampers seem to be the 2 biggest problem areas.

Replaced the damper and cap top. Check the line that runs out of the pump to the drain bottle for plugs. What color are the lines on your pump? The old pumps had white lines and were a problem.

Sorry to hear that you are having problems with you VersaCAMM printer.

First, be sure to locate where the ink is leaking. Usually, when the head printer goes bad, it leaks thru the head. However, this is not the only issue that it may cause the problem.

I'm not sure what model number do you have, so I'm providing a generic solution.

* Check for cracked manifold stems, if cracked, replace cap tops, stems and damper. Better if you replace all.
* Replaced yellow damper/Syringed ink to create vacuum.

If everything looks fine at this point but still having problems, then you need to go technical:

* Power off the equipment and look for blown fuses. If any, replace it. Keep a few fuses handy in case it blew again.
* If fuse were replaced but it breaks again, there is a short circuit in the board. The board (an expensive one) may need to be replaced.
* At this point, a technician with experience in component level repair may need to check this printer.

Hope this helps, Good luck.
