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...

Which direction are the banding lines, in the printhead movement direction (horizontal) or the feed direction (vertical)? I would suggest adjusting the media feed compensation. It's called Distance Adjust in the Mutoh. On most printers using straight line pass printing, you see light or dark...

Perhaps some clarification on ink longevity... The 6-8 months lifespan is typically for water based pigmented ink outdoors. Prints done on these type of printers, i.e. Canon, Epson, HP, for indoor use have a much longer lifespan, i.e. in the 25-100 year range or longer, depending upon the...

Call Mark at Sign Outlet Store - (630) 737-0146. They are the local Roland dealer. They are located in Lilse. Tell them I sent you. I've done some work with them in the past. They're good people. Regards, Jim

I know this may sound crazy, but what actually works very well for cleaning encoder strips is acetone. You will need to remove the encoder strip from the printer to do this properly. If this is a JV3, you will find it easiest to remove the bracket that the encoder tension spring is attached to...

You are absolutely correct. I just installed 2 DX2 heads in a Roland SC-500 last night and that was the case. My heads had the head rank, a 5 digit number, on the side, but also on the inside wall above the damper posts, in black as Tomence said, so it may be hard to see. Regards, Jim

The number on the top is the head rank setting.

I would need to know exactly which model you have to advise you. It would involve hooking the suspected head up to a different channel on the printer. You are now entering an area that should really be dealt with by an experienced technician on-site. I don't know your level of technical...

The LED's in the Celestron's lighting have enough of a blue content to make it very easy to see yellow, so no need to do anything but look at the screen. Hey Trent - staying busy in the warm where 50 degrees is like a blizzard for us.

If you are checking it because you are blowing fuses, then you do not need to remove it from the board, as it is shorted and will read zero ohms across 2 legs, even while still in the board. If you are checking it for any other reason, you will nedd to remove it from the circuit to get an...
