I would suggest cleaning the encoder strip with acetone and a microfiber cloth. Let us know the results...

Is this the same printer you have been posting about? - RF640 - Nozzle Check (Test Print) Serious trouble | Signs101.com: Largest Forum for Signmaking Professionals If so, you likely have a defective ribbon. Look for any ink residue around the connector area, examine the ribbon contacts closely...

Yes, it would be easier and cheaper up front. But remember, electricity surges can and will go anywhere. If the OP has lost 3 routers to surges, it's only a matter of time before something else gets hit. I suggested UPS systems from previous experience running a shop with 23 printers of various...

The i1 Pro3 Plus will do backlit materials when using i1 Profiler software.

Except I am a big fan of acetone for cleaning the encoder strip. Try that and let us know. Solventinkjet try it, you will become a believer... As to the problem, did I understand it is on different medias or just one media? Did you examine the media with the issue in areas before printing...

First, printing to wide format printers will work, but not well. The printer will likely outrun the data stream from the wireless and will hesitate for a brief time at the end of each scan. Second, it seems your main concern is frying your routers due to surges from the cable line. Your best...

Great! Thanks for updating everyone!

You have any of several issues, i.e., clogged cap lines, bad heads, blown fuses on the mainboard, cap/head misalignment, etc. I would suggest you call me to discuss, as there are many potential issues. It will be more efficient to help you verbally than through multiple responses here. Once we...

Not exactly sure what this means... The primary purpose of this board is to share knowledge and information, whether it be hard earned through experience, or knowing what existing information is available that will help fix the problem. Many users on here are not technically oriented and come...

See attached file. Please post your results...

The first thing you need to do is to clear the lines between the cap and the pump. Ink remaining in the cap is an indication of a clogged line. Once that is done, post the results.

OK, clarity of what you are doing is very important when troubleshooting remotely. You need to pull ink through the dampers themselves, not the ink line, so you are getting them full of ink and getting the air out of the ink lines. The dampers need to be about 3/4 full of ink at a minimum. The...

Are you tightening the screws after making each adjustment? If you aren't, as soon as the heads cap, the pressure from the capping station will move the heads.

There is almost always air in the top of the ink cavity in the dampers and it is OK. The important thing is the output from that cavity is completely covered with ink. I would check the cap, making sure it is clean and correctly aligned to the head. Is the new cap OEM or aftermarket? Captops are...

Pulling ink through the dampers is a very valid technique for determining problems and also shortening up ink charging. You said the ink retreated back into the line after removing the syringe from the damper. This should not happen. It is an indication you have an air leak. Did you replace the...

It is most likely your problem...

Always more than one way to solve some problems. Glad to hear!

Do you have a way to replace the transistor?

You will definitely want to see it print yourself. I would suggest the following printing tests. A test print (nozzle check), the fill test in service mode, and the attached Onyx quality test printed at a standard setting - 720x720 8 pass bidirectional. See the attached file to enter service...

You have issues with 4 heads - black, yellow, light cyan (multiple missing nozzles) and light magenta (heavy deflection). Were the test prints done while you were there and at what settings? You are looking at least $2500 to bring it up to spec, and that is just heads, dampers and labor. Not...
