Hi everyone, I have been using a L25500 for a few years and a L26500 since March.
Im getting this wave diffect that i have never seen before, its done by the top metal rollers,, because the waves are consistent with the rolls print.
the horizontal banding I already fixed with some temp adjustments. The waves I cant fix, and both the L2500 and L2600 do them.
Any advice?
Chafro, that photo is mine. The print was done on my Latex L25500 machine, I posted a question with that photo on another forum. I don't mind you using my photo if it helps you work out your issues with your printer. So, your prints must look like my prints did since you used my photo?
The material is Kapko 13 oz. banner material. I discovered later that it was stored for some time in various temperatures and that could have added to the problems I had with my prints.
I did try some of the ideas suggested by the forum members where I posted my photo. I changed profiles, messed with temps and increased ink passes. Also, tried advancing the material a bit before printing, and unloading material when finished printing. As I got deeper into the roll of material, I did get better prints.
Someone else even suggested that it may be a static problem. Not sure about that, but I do remember quite a bit of static coming off the roll, so that could also have been the problem.
Since the time I'd originally posted that picture, I did find out (didn't know it at the time) that I started with all bad heads on my brand new machine. They have all been replaced since, I even lost a replacement one a short while ago and replaced that too. With the help of the HP Techs over the phone, I also did the firmware update for the L25500 machine. I've also changed the sleep mode settings (per HP Tech's advice).
I had saved my original print head alignment tests that were done by the Tech who set up my machine and compared them to alignment prints I had done myself later on, after replacing all print heads. My tests were much better and proved that the jets were not firing ink properly in the beginning. However, I didn't know that because I had nothing else to compare those prints to in the beginning. My Technician never came back after initially setting up my machine and the Company he worked for went out of business shortly after I got my machine.
So, I had to work all of that out with whatever help I could get from forums. I really appreciate the forums for that reason and everyone who helped me.
Anyhow, hope you get your problem resolved. Let us know what you do to fix the problem.
