Distilled water and ultrasonic bath for 1, 2 3 minutes. If the can select power start on a low setting. To much power can damage them. I use cold water as I don't know if heat will do something unhelpful to the blocked nozzles. It the heads have damaged foils there is no way back. You can use a...

Take the heads out and reboot. Put the heads back. One may be faulty. Also if Chinese swap chips for hp origional from printheads.

There are some interesting suggestions here. The shims are spot on I think - no play apparent. I'll check the screws and then do the small belt. I've got belt material with the right tooth profile so I think I can make one up. I agree it better to use oem parts, but cost is also a factor. My...

What things wear and reduce the accuracy of summa cutters? We look after a summa cutter. It's generally cutting lots of circular stickers about 2 or 3 inches diameter. I'm told when it was new was accurate on large sheets, and would cut at high speed. As its worn the speed has to be reduced...

I'd change the main board. Maybe a dry joint.

Just checked the summa spec Its 0.2% which is disappointing. We are about 1500mm between the corners, so 3mm is within the spec of the machine. That is really underwhelming. I'll check calibration. I am fairly sure the cutter are more accurate when new. Due to our inexperience and the age...

Hi we are cutting a sheets of printed circular images on a summa s160t Media about 54" Diameter of circles about 50mm We're losing tracking as it proceeds through the print- the cut circle is moving away from the printed circle. It's about 3mm out along an axis about 45 degrees. We...

We had an issue with a s160t On start up the carriage would just twitch then the machine would error. The issue was the encoder at the base of the x axis drive motor. It had cracked and become detached. We did manage to re attach it at the cutter sort of worked but not well, losing...

We have vertical banding in l28500. I went nuts trying all sorts of stuff. Then I noticed on a 2.3m wide print which was all black, that the banding was not across the whole width. The bit on the left hand side was good free of banding The vacuum bed looked clean but I attacked it with various...

79.04 I'd start by removing heads and rebooting. Then put heads back in. I suspect a head has gone faulty. This process should show you which one.

Could be a few things. Carriage felt pad distorted and causing excess friction. Or idler pulley bearing fallen apart Or something else.....

We have the carriage Bristol inkjet ltd We ship internationally. Regards Bristol inkjet

I've had load of trouble with vertical banding. Failed to sort it, after many attempts. Stuff went out and was just about accepted. Then we put on a new roll of media. Suddenly everything was perfect. Good luck

Not worked on this model yet. But we both our printheads is cold water in an ultrasonic tank. Ours has a veritable power facility. Start on low power for a minute. Test. If no improvement maybe longer or more power. I don't like full power as the heads have ceramic parts which might crack if to...

It's an interesting question We refill cartridges using a peristaltic pump. We overfill then a day later after standing pull out the air and excess ink. We now have changed as I think air gets mixed with Ink and desolves. A small amount of Air in the cartridge may not be do serious as it...
