After rebuilding my R-Jet 5 with new mobo, head, cables etc, all seems well. Apart from the fact that the heads need aligning!

Can anyone tell me how to best perform a manual alignment with this machine?

Thanks!

Hi, The head should be aligned if fitted correctly.

What symptoms are you seeing that look like the head needs alignment.

Hi Colin

Thanks for the reply - please see the attached images - you can see that the black looks blurred due to the double print or ghosting. I've tried two heads, and they're both the same. I'm sure they're fitted OK. Is it some sort of alignment issue somewhere?

Ah - I've just considered that the encoder strip could be causing an issue... I have a spare - I'll replace it and post back!

Hi,

Are you printing that test sheet using bi direction? A good indicator is your nozzle check only prints in uni direction. If that’s not blurred or double imaged what you are seeing is bi directional alignment.

You can run a bi D alignment but the printer is set to a specific head height. This is more than likely the issue.

Hope this helps.

You had it spot on. I reset the PG using the maintenance mode. It now prints brilliantly.

However, it’s raised another issue. The carriage raises to clear the platten when printing. As this height is greater than the default setting, I assume it’s either set in the firmware to raise or the RIP instructs it to do this upon printing. Anyway, the issue I have is that when trying to run a head clean or nozzle check, the carriage doesn’t raise to do so and strikes the platten.

I can get round this by running the PG utility and manually raising the carriage height and saving it, it’s then ok to head clean etc, but prints badly.

Any thoughts? Is there a setting somewhere that needs adjusting?

Thanks

In the manual, towards the back is a page that shows all the correct default settings.

I think you just need to go through those as the reset may have wiped out your defaults.

Hi Colin - I appreciate your help!

I checked those - all OK. I popped the old board back in to check the carriage movement etc and it raises the height of the carriage to clear the platten as you'd expect. It doesn't drop to the original PG setting as the other board did, so this behaviour is set somewhere on the board other than the NVRAM - but where?!? More importantly how do we go about transferring it to the replacement board?

Hi,

Are you talking about the main board, if so it is modified and cannot be changed for a standard Epson main board.

Let me know.

Hi Colin, yes I should’ve made that clearer. I’ve replaced the main board after pulling the NVRAM from the old one and flashing to the new.

It all seems to work perfectly aside from this pesky PG issue when head cleaning or printing a nozzle check.
