Using spare LED lights to illuminate your printer.

Might be of interest to some...

Had an issue printing grey on CMYK machine. whilst printing in my studio under the tube lighting print appeared grey. Once took into day light had a nice green. Resolved the colour issue but delayed the job. I have now installed led lighting onto my Roland. Its easier to clean, get media through, check colours and who doesn't like LEDS.

There are 10x 3led modules (left over from an illuminated job) and a small 30w driver. I have installed the LEDS onto the guard as its the only location that gives plenty of clearance. I have covered the leds with a thin silver vinyl strip.

Not for everyone but has a practical use for me.

Re: Spare LEDs to illuminate printer

You need to ensure your LEDs are giving off the full spectrum of white light as many don't. e.g some are warm (red end of the spectrum) some are cold (blue end). I'ts always best to check colours in natural daylight

Thats a good point, I only installed lights to check the quality of the print / difficult materials are behaving. prior to the leds you couldn't see in there!

It's It's a good though, nice one!

HP 360 latex machines come with this as standard. Wouldn't be without the feature now, all printers should have them.

Re: Using spare LED lights to illuminate your printer.

Would love to see a close up Jamie.

Been thinking of doing this myself as I had seen someone else do it some time ago.

Do you have a switch to turn it on or does it come on automatically?

Re: Using spare LED lights to illuminate your printer.

Hi Daniel,

It was a spur of the moment sort of thing and so no switch currently its on its own 3amp plug.
I was thinking of modifying it and putting a 12v switch on the cables running from the transformer as I unplug it at the end of the day currently.
Other issue i have found is that due to the location of the module installation (no favourable other location to use) when the dust guard is raised it blinds me! I can however feed material without opening the dust cover so not a major issue. Perhaps a switch on the dust cover to turn of on opening but then back to feeding material in poor lighting.
So yes a work in progress possibly.

But plenty of light! I routed the wires opposite side to dock from the dust cover over the top of the machine and down the leg into to the lower brace where the driver is situated.

As Phil has correctly pointed out LED's are available in different colour temperatures, the attached scan may be useful.

I presume the same issue applies to standard unit / office lighting also.

Re: Using spare LED lights to illuminate your printer.

Yes it does, Ordinary flourescent tubes are not generally 'daylight tubes' and equally the sames applies to ordinary light bulbs. Daylight tubes are available as are incandescant light bulbs, I've been using them for over 20 years and more recently daylight LED lamps.
