Roland SP-300v Head Problem?!?

Post by chri55 » Mon Jun 03, 2013 11:11 am

Hi all need help Identifying / fixing the problem with our Roland SP-300v printer.

The problem is mostly with the black. I suspect the head is blocked but don’t know how to rectify this, without spending loads on a new print head.

I’ve read some forum pages where people do a head soak / or use flush cartridges. But as this is something I’ve nether tackled before and I’m a bit concerned about making the problem worse.
Being out of warranty I’ve had to change parts in the past with success, these parts are the usual things like the linear strip, the strip sensor, pinch rollers, the media width wire that connects the cutting tool to the main board at the back of the printer and the usual throw away cleaning parts like sponges and wipers. So I’m able to get into the service mode as well if this helps.

The printer heaters run at around 42-44 and changing this setting does not seem to affect the print quality to much.


Now the printer is about 6-7 years old and the black has for years now had a small amount of 'Blocked' nozzles but in the last year become steadily worse. It now seems to produce a hazed / blurred edge instead of giving crisp one like it used to.


Here is the test print taken this morning after the printer was manually cleaned followed by a 'medium' head clean:

Also no matter how I seem to try and align the print and cut it's always been slightly out of alignment, How can this be corrected?

Thanks in advance

Your picture doesn't show. 6-7 years is pretty much the max amount you can get out of a black head.

Print-cut alignment is a more complex issue, it can be static, blade/holder/protector issue as well.

Sounds like the head will need changing...
If you want a Roland Engineer to do this for you, give me a call on 0845 230 90 60.
Also a RolandCare warranty maybe worth looking into... Using our free pre warranty inspection visit, you can save 30% off our RRP parts used to bring the machine back to life and no call out or labour costs.

Good luck!

Yea, that head is done. Also, some missing in yellow. Make sure you have the captops changed as a clogged captop may prevent nozzles from cleaning and it could be permanent.

Hi,

I have encountered a similar problem with the head test print you have shown, the way we got around this was:

1) Try a power clean, medium clean or a normal clean, if these do not work-

2) Try flushing the ink via the maintenance option, all in your manual, if that does not work-

3) Try replacing you ink cap, felt wiper and also the rubber wiper? This fixed our problem, i did some history work on our machine only to find that it had not been serviced for years and due to this the ink cap had become saturated with ink so when we tried to clean our head with a cleaning, it just made the head worse.

This may sound complicated but to replace the wiper, the instructions are in the manual and to replace the ink cap, i watched a Youtube video on how to do this (ok this was a different model but the same concept).

I used Granthams for the part, it cost us around £100 in total for the ink cap and wipers, put in ourselves and to be honest, it is like a little mini own service on our machine and it now works amazing, nice smooth gradients and halftones.

Hope this helps?

Phil.

Usually, when the clogging appears in the same horizontal row of nozzles it's mechanical damage to the head that's causing it. The head has hit media clamps or similar. You may check the head surface with good flashlight and if there are noticeable scratches it's not reversible.

Does look like an issue with the black head, what does the nozzle check show.
