Make sure the fuses you checked are those in the attached pic (look for the red outline in the pic), as these are the fuses that supply voltage to the printheads and there are only 2. If these are good, have you tried to gently pull ink through each cap individually? Depending upon that test...

Start by initializing the limit - hold left, right, up arrow keys and power on, follow the prompts. Then, as stated above, run the encoder setup and calibration in service mode. Let us know...

See attached for details. It looks like you may need a good Roland tech to come in.

What is the tested outdoor durability of this ink compared to the current solvent & ecosolvent inks?

Also close off the line for the cap for the missing head, or the cleaning cycle will just pull air.

Not familiar with the Polar printer. More info needed for that, like a model number. Try Google searching and possibly Alibaba for info. Alibaba will probably be best as it's Chinese...

That is a good troubleshooting technique to narrow down the issue. But, after switching the dampers, did you do a cleaning, preferably a medium cleaning to flush the other color inks from the head? If the test print done after this is K/C, but physically where the M/Y normally is, then you have...

That would make sense, but the title had it correct. My point being there is a lot of info thrown around by various posters who don't do their research and make sure what they are posting is accurate. I have seen answers that would actually cause more issues. As people who ask for help are...

Apparently you are not familiar with the Roland printer line. That model was a very popular printer and a workhorse machine. Please check your information before posting to insure you are not accidentally misleading someone. As far a good price, I would do a web search for that model being for...

Please post pics of the various issues...

I would replace all the sponges and the captop, redo the cap adjustment and report back... Perhaps solventinkjet.com has some additional thoughts...

Have you examined the bottom of the print head for physical damage or ink buildup on the head surface? What condition is the cap in, perhaps it should be replaced...

You need to take a systematic approach to solving this issue. Also, the protect the pump message just means the pump motor needs to cool off. I would suggest you try pulling ink through the magenta and yellow dampers to see if the clog is before or after that point. The following items will be...

Epson sometimes implements codes into printheads that restrict them to certain printer models, especially the aqueous heads. This is likely your problem.. The DX4 solvent version heads can be used on water based heads. If you buy an aqueous version, you have to change the manifold to a solvent...

Replace the ribbons with new ones and let us know...

That head shouldn't be used that machine. The solvent ink will start to melt the manifold and you are going to get plastic residue in the head, at which point it will make an interesting paperweight. The solution is to buy the correct printhead.

The big thing is chips that still have ink life. The cartridges don't have to have ink in them, just put tape over the area on the cartridge where the empty tab comes out. It's in the lower front side of the cartridge. Or using refillable carts will work, but an additional expense.

Nope... it must have cartridges with chips.

Excellent post. Very informative and clearly written.

Your print quality is impacted by 2 factors - image dpi and printer quality setting. For general sign work that is viewed at more than 5-10 feet away, at the same printer quality setting, you will not find any dramatic improvement above 150 dpi image resolution. If you are doing prints that will...
