They come off quite early, and are held in place by a single spring-spindle. Removing the star wheels is easy, if you are prepared toĪ) remove the upper front cover (quite easy)ī) quite physically flip the star wheel tracks into the active, down position,Ĭ) and then with a very thin and long pair of needle nose pliers gently coax each pair of wheels out. I tested this out while a sheet was printing, by sliding in a long scrap of paper about 5 mm above the output bed in the vicinity of the sensor, and sure enough, the star wheel bars dropped down and remained down for the rest of the print run. The star wheel bars (two of them) drop down near the exit point of the print, when a sensor located in the front-right area, just before (towards the print head) the bars, senses paper that is curling upwards. I think I have everything working! Walker, thanks again - the trailer sheet is vital to avoiding star wheel tracks but with a number of other steps with the 4900, which I describe below.

#Epson 3880 printer settings media type baryta paper how to
I am now deep into the service manual and trying to figure out how to disable the drop-down of the whole tracking bar, or even if/how I can actually remove the star wheels. Each star wheel is on a spring-spindle, so pressure applies regardless of distance from the exit rollers. I have tried attaching a front sheet too, a ‘leader’ leader, in the hope that the weight of the leading sheet would hold the film down and away from the star wheels, but that too does not work and leaves a mark. The bars that hold the tracking wheels drop down soon after the sheet begins to go past the printer head track.

The wheels, what looks like two or three sets of them, are at the front, near the exit point of the printout, and downstream of the printer head. But after your pointer about the location of the star wheels, I ran another sheet (leader + Pictorico) through and watched the guide wheels with a flashlight. I have the leader paper hang out the back over a table edge, still getting tracks. Thanks in advance for any suggestions / guidance!Įxcuse the rough iPhone photograph, but I hope it sufficiently illustrates the problem: I have look around for a similar hack with the 4900 but have not found one as yet. Has anyone else had any experience with a 4900 doing this, and if so, are there any solutions? Both Walker and Keith have presented whats seems a great solution and instructions for resolving this problem with 3800 printers. Have rotated the target image by 90° just to be sureĪnd there is no difference - the star wheel tracks keep showing up in the densities. Have even printed an 8x10" target in the middle of a 13x19 P UP OHP sheet with a leader Have printed at the very bottom of the sheet, as well as the top Then I did a thickness test with Pictorico film and fine tuned the gap to #1.Īttached leader/trail sheet that is at least 50% longer than the Pictorico UP OHP film I have adjusted the platten gap, first to ‘narrow’. I feel sure they will show up on a pt-pd print. I tried the method described in >Piezography>Documentation>InstructionsĪnd it certainly made a difference! But I am still seeing* (albeit finer) star wheel dots in the latter half of the sheet (*after heat drying + 1 hour). Thanks Walker, for this suggestion and all the other help you have given me as I slowly (my fault) get up to speed with Piezo-DN. LOL.įor me imposed wide margins are no big deal: I like the presentation. In the future I might create a more elegant spacer out of museum board to remove this step in the exit path.Īlso I decided to remove the front load paper guide because on my printer the suggested ramp did not work and I experienced a head strike on the trailing right side of the print as a result of the ramp lifting the paper.Ī pair of lightweight flush wire cutters allowed me to nibble the right front paper guide away. A small spacer (I used a folded subway map) was required to prevent this counterlevering to develop into a buckle in the paper that might further lead to a head strike. Also there grew a possibility of scuffing a wet print, especially as the print counterlevered over the step created by the front load door and the exit paper tray.

I found that the “optional” step at the end with the hinged guides to be mandatory because these two tabs consistently caught the front edge of my paper to begin trying to effectively fold my print. When the switch gets activated the process continues and the request to close the door goes away. Having the printer on with the front load door open stopped the initializing process that happens upon initial turn on. I found by probing with a take-out chop stick that very little pressure is required to set the required switch. This allows me to replace the side cover.

I used a disposable hearing protection ear bud to set the switch.
