Reassemble the cutter head and bearing block, if you haven't already. Now, move the cutter head at slowly and listen to see if the clunk repeats itself at a regular interval every couple of inches. If so, as mentioned by cornholio, clean both belt pulley wheels, looking for something to be stuck...

I'm not sure what you mean by this. Did you remove the cutter head from the bearing block? Once I understand this statement, I can suggest something...

Either the bearing block for cutter head has buildup inside or it is going bad. Try to flush out the bearing with alcohol. Take a syringe and gently squirt alcohol into either side, top and bottom, while moving the cutter head back and forth a small amount to try to remove any buildup...

When you did the Initialization, did you insure the head carriage was locked in place before starting the steps? Clean the pulleys with alcohol. Also check the belt itself and make sure there is nothing stuck in the teeth anywhere. In addition, clean the guide rail with alcohol, make sure to...

Assuming your printer is new and under warranty, the dealer needs to fix this issue. This appears to be an electronic issue revolving the print heads.

You're welcome!

It's a mechanical lock. Using both hands (more movement control) push the carriage SLOWLY into the home position. You will hear two faint clicks, stop immediately, and then put your hand on the right side of the carriage and try to push it to the left. If you are successful, it will not move. It...

Just lock the printhead carriage into place over the capping station. If you are having trouble locking it, as it can be tricky, just push the head carriage all the way to the right. this will raise the capping station mechanically and you should be good. A suggestion - as we don't know how long...

Based on the picture of the bottom of the printhead, it does not appear that the head is being wiped... Please attach a pic of the wiper.

I do remote phone support with a primary focus on Roland printers. If you feel comfortable working on you own printer, call me to discuss...

That is correct. The ink end sensor arm is a 1/4 inch in height, so the opening should be a bit larger than that, otherwise the arm will not drop into the slot to monitor the ink bag.

Here you are... It will be a bit of trial and error on the trimming, as you cannot see the sensor arm very well with the cartridge installed. Be careful not to cut the bag!

This is common after installing a new head, before doing the head alignments in service mode. It is fixed when doing the 3rd step - horizontal. Also insure you positioned the print head as shown. Once all 4 alignment steps are done in service mode, your overlap should be gone.

Thanks Joe! I've had the sensor checked in service mode, but I think I'll see if there is another sensor of the same type in the machine and swap them to see what happens.

This is a VersaArt printer that prints only. I would assume the sensor you mean would be the Sheet Load Sensor in this case? I'll check. Customer has ordered a NEW encoder sensor, hopefully that's it...

Good thought! Had my customer check the belt tension just now, doesn't deflect more than a quarter inch.

I have a customer with an RS-640 getting the position invalid, out of range error when doing the limit initialization. The problem started with the 0080 scan motor error. Now, when running the Initialize the Limit, the head comes out about an inch when running the "setting up the limit" step and...

1. Run the Initialize the limit. 2. Run the linear encoder and calibration in service mode. 3. Clean the cropmark sensor with alcohol and a foam swab. see pic 4. Try the print-cut and crop-cut alignments again after the above steps. FYI, Oracal 751 is a cut vinyl material. You should be using...

Did you run the limit initialization after replacing the encoder strip? Please, never use water or cleaning solution! The encoder strip is a piece of graphics film that is processed in water-based chemistry and water and cleaning solution will soften the emulsion and can permanently damage it...
