I'm responding to your surprise when getting 'apparent' head strikes when printing the last inch or so of the print. When printing to this end region, the paper is not held down by the rollers. This permits the paper to lift up slightly and get struck by the print head--especially at the corners. flattening the paper under a pile of books is useless. It will necessary for you to apply a reverse bend at all 4 corners, you will not just force it flat; you will make sure the pressure applied by your hand will bend the 4 corners slightly backward. This if done satisfactorily will eliminate head strikes both at the beginning and end of printing. Do it or continue suffering!

Hello, many thanks for your advice. You are right, and I have some other attempts to report:

- I have done the head alignment and I found that my settings are ranging around 3 (instead of the central 5 value). As per what you know are head alignment affected by head paper strikes (i.e. I have to check it always after hearing heads strikes)?

- Unlucky I have tried again the book flattened HM PRPearl paper sheet and even the 4 corners hand decurl additional workaround you suggested was not enough. Printing with 0.5thick+"std"pltgap and feeding it in the front tray was still not successful: I aborted the print due to head strikes noises. It seems that "wide" pltgap is mandatory with this damn paper.

- Curiosly I have then tried to print a calibration pattern via QTR on another sheet of this same paper, feeding it via the sheet feeder (because QTR gave me an error for the front tray), and it was perfectly printed without head strikes noises. This is wondering because there are not dedicated settings for thickness and platengap in QTR to play, so this was with some (unknown to me) default QTR values for these settings.

- Canson Rag (MK) and HM PRBaryta (PK) still printed out the QTR calibration sheet without glitches from sheet feeder.

- finally, for the sake of curiosity/consistency, I printed again a Canson Rag (MK) and HMPRBaryta sheet feedeig it in the front tray (with Epson driver at nominal thickness +"std" pltgap) and all was perfect as always with these paper was.

So what the conclusion can be now after four days of mixed attempts?

Ok, ok, I know: avoid the problematic paper, get a life and go on...!

Please understand thoroughly that the manual is a basic guide--it is not the Bible. Listen to the 'flock' of members on this site--we have walked thru the wilderness, climbed over the mountains and baked in the deserts of 'printer world'. Nothing here is cast in stone! By using a Colormunki (or other device) you can create a profile for printing on kitchen toweling or toilet paper--or in more familiar terms you can create a profile for glossy paper while specifying Luster or Semi-glossy or even Matte as the media. The media selection affects the quantity of ink that the printer will lay down for given media, the icc/icm profile determines the color correction that will be executed between the image file and the printer head.

Yes, this is very reasonable, I have understood, many thanks.

Please, step back and take a deep breath. Re-read the suggestions given here, try them again and again. There is no meter running, we will assist you any time you ask.

I agree, I will try to relax a bit

The problem is that I have only few days to figure it out if I can deal with this printer of if I will consider it defective and send the printer back, so these days are quite busy for me.

I promise you that after having solved this issue I will take it easy, whatever decision I take...

Remember, this too will pass.

Ciao, irv weiner

So true
