If the dots don't seem to be in the same location, then put back the first photo - but this time put the photo in rotated (the top is now the bottom, and the bottom is now at the top) and if the dots are in the same location again, then there is something on the photo that you may be over-looking, like dust or small scratches.Īnd finally, if the white spots have totally moved, it is just dust. The glass might even have a small nick in the glass, causing flares in the reflection of the scanner light.
If the dots remain in the same location, then put up a new photo and see if the dots are in the same position but just on another photo (you will need comparable dark areas to detect them) you have a dirty platen (the glass). If the white dots move (not appear in the same location on both scans) then you have an interface or scanner problem. Have I encountered this issue before? No.Scan the same photo twice, without moving anything. Heating System in Place: Yes 3 heaters temp controlled.Īmount of rolls printed before I encountered problem: About 3 Rolls. When I removed the cover and checked the print heads there was tiny bits of dust all over the printhead and surrounding areas. White spots on the print will be caused by dust on the negative, lens, or paper - If these are small and infrequent, spotting dye and a fine brush will hide them. I thought it may be the dampers but now I think it could be the static build up because I do pull the power plug off the wall when working on the printer. I have tested 3 different rolls of material and its the same issue on all so it is not the vinyl. We told ourselves it's the printer paper, but as of late, we used Navigator Printer presentation paper and still had the same sort of result. So either the dampers are contaminated with something or its something else.Ĭan't remember but within 24 hours of changing the dampers when I touched the printer switch to put the printer on it gave me a stong static shock. We've tried printing solid colors (pink) on different printers and they all seem to come out with white specks on the pink.
This has only started since I changed the dampers. I have attached an image with a sample print. The only issue I have right now is the white spots. I initially blamed the dampers in which I have ordered some more but I am now thinking it could be the static and if it is how do I fix it it? Has anyone had this problem and has found a fix around this problem. I increased the heaters slightly but has not helped. A day or so latter I checked the printheads on the printer and had noticed a bit of fine dust sitting on the print heads, pump tubes etc which I blew out with a an air gun.Ĥ.
I have used 3 different rolls of material and I still get the same issue which rules out the vinyl.ģ. I remember either on the day or a day after or a day before hand I touched the printer to switch on and I got a small static shock when I touched the printers control panel to switch on.Ģ. I am not sure if the dampers were contaminated but I can only point this issue to a few things.ġ. The printer does not print white but the area has not been filled with colour. I started to get white spots on the print. The most common causes for banding, missing dots, and white streaks in printed output are listed in the table below: HP has indications that the lubricant on the printer carriage assembly tabs and the flex circuit contacts on the print cartridge can collect debris (fibers and dust), which may cause poor output. is usually carried out on white fabric so printing white dots on a black. I checked the dampers and these were loose so I changed them, problem fixed and back to printing I went. What is more, it is basically impossible to print pictures using the screen. Everything has been going well until one of the colours dropped out.
