An Attempt At Writing A Realistic Review
on 17 May 2011
I will write about a well-established problem with this gadget's operation, specifically the inconsistent image quality and the dreaded streaking most owners experience at some point. I'd like to help others get rid of this frustrating problem too.
So I got some good news on this. I've received my PoGo a couple of days ago and have been working on it to get rid of the unacceptable amount of streaking I suffered from the second or third print on.
Examining, testing, printing test pics, etc. I have finally come to realize the method suggested in the manual to clean the printing head/heat plate does not quite work the way it should. The fine dust stays in, being not a dust friendly design it messes up the printing performance. The streaking is almost always about the fine dust particles gathered on the heat plate, not about the paper however old they happen to be.
The trouble is a simple design fault with the springy pressure plate underneath the lid. It's supposed to apply enough pressure on the paper to both print clean pictures and to clean the heat plate with the blue lead paper that comes in each paper stack. Basically it neither quite covers the whole width of the paper nor applies enough pressure on the papers or the blue cleaning/calibrating cardboard to perform the cleaning action.
I have found a consistent solution for this that worked perfectly for me:
Always keep the blue cardboard calibration/cleaning cardboards when you open a satchel of papers. Turn the printer on. Open the lid, empty the paper bed, slide the blue paper towards the slot as suggested in the manual. Don't close the lid but hold the little switch on the opposite corner down that tells PoGo the lid is closed. The roller will start working with the lid open and you'll see it begin ejecting the blue paper through the gate. While its pushing the blue paper out gently rub over it with your finger in a left-right-left-right motion along the inside wall above the roller till the paper gets ejected fully. This is to apply some extra pressure so that the fine dust particles collected over the plate do get stuck on the paper, cleaning it. Then place the papers back and put a couple of (two or three) blue papers on top of the stack to increase the thickness of the stack, therefore applying some more pressure via the springy plate at all times. If the streaking is heavy (you got too much dust in the slot) do it more than once before printing anything.
As a final note, the top and bottom edges of the paper that are not covered by the breadth of the springy pressure plate inside are more prone to streaking so if you get those try a little bit harder with the manually assisted cleaning process.
And so, ideally, whenever you get a streaky print first go with the cleaning process with a ZINC paper with the bottom facing up and then a second run with the blue calibration/cleaning cardboard. And use a couple of blue sheets on top of your paper stack at all times when you insert paper.
I know it sounds like a hassle but it doesn't take more than another 60 secs to make sure the next print gets out properly saturated, vibrant and streaking free. And although at varied intensities this is probably a design problem all units will suffer from at some point. Replacing the unit won't make too much of a difference I'd guess.
Once you accept this little bump, the PoGo is quite fun and I'm actually enjoying it quite a bit when it works the way it should! : )
