This looks like static to me. Questions... What is your head height? Does it do this on other media?

The solid stripes of color and the nozzle test print indicate you have printed the fill test in service mode. Based on the look of the cyan and light cyan bars, those 2 print heads look like they are dying. To fully understand the difference between a good nozzle test and bad printing, use this...

I would not recommend swapping cables on the single head, as there is internal circuitry in the print head that is different from one side of the head to the other, such as head temperature circuitry. However, along that same concept, swapping the ribbons from the magenta/yellow head with the...

Erikka is on target. What you are most likely seeing is the result of the banner material being slightly squished and flattened by the rollers. This is causing a microscopic thickness change in the media and changing the printhead to material distance. This results in a tiny variation in the...

Your problem is most likely light reflections off of the fabric itself. I recently tried to profile a dye-sub printer with an i1 and got a very spiky curve on the yellow in the linearization. This thread will give you some clues -...

Cleaning the encoder strip should NOT be done with a water damp cloth. The strip is a precision piece of film and water can actually cause problems. The best solution for cleaning it is a microfiber cloth and pure acetone. Acetone does not effect the emulsion on the encoder strip (water will!)...

Shut your printer off completely and pull the cyan ink cartridges. The odds are one of the cartridges is empty and the flag didn't come out and trip the ink empty micro-switch. The reason for turning the printer off is the internal ink level display won't be reset. You may have to do a power...

The tool carriage ribbon is most likely going bad. Inexpensive and easy to replace.

The capping adjustments under #adjust need to be done to insure proper operation, however these adjustments, including the height adjustment, do not change the left-right position of the head-cap relationship. My experience has shown the caps tend to end up too far to the left over time, due to...

Your problem is most likely a centering adjustment between the print heads and the caps. You can test this doing the following: 1. Power off the printer. 2. Clean the bottom of the print heads gently with cleaning fluid. 3. Wet the edges of the cap tops with black or waste ink. 4. Manually park...

Where did you find them?

VW I'm assuming means VersaWorks is a Roland only product. It will not work with the Mutoh...

I agree with Gabriel's advice except on one account. You do not want to pull hard on the print head through the cap. You take a chance on fracturing the print head internally! I speak from the voice of experience having had this happen on a brand new print head.

There are 2 types of transistors that control the print head, the C4131 and an A1746. These can be measured in the board with an ohm meter. If they are bad, you will read 0 ohms on at least one pair of leads. In addition, there is a 43 ohm chip resistor that goes between the base and emitter of...

I am having this same error on a customer's RJ900. Isn't the y axis for the head carriage? Would like to confirm before I order a replacement motor. I'm also getting an intermittent knocking sound, which I believe may be a stretched paper feed belt jumping teeth.

CJV30 & JV33 use the same print head. The CJV33 is the print-cut version of the JV33.

You might consider changing the outer pinch rollers. They are slightly angled when new and tend to wear flat over time. The angle is there to push the edges of the media outward and help keep it flat. When the rollers wear flat, there is a tendency for the media to wander, most especially during...

I don't think you are following the proper sequence. Look at page 4-16 for the keystroke and main power button sequence to install the firmware on a replacement mainboard. Then see if the procedure starting on page 4-17 to upgrade the firmware also works for installing on a blank board. I don't...

I would check the firewire cards and see what chipset is on them. The Mimaki firewire card was designed to work optimally with a pc card using the Texas Instruments chipset. This info comes to me from my contact at Mimaki corporate, and it works. I have a customer who runs a 160SP and a 160S...

Don't remember for sure which way the lines show when the dist adj is off, but give it a shot and let us know... I believe the effect is a harmonic of the wave pattern when the feeding distance isn't correct. Keep in mind that this setting can change the actual length of the file, so once you...
