The paper you scan is stuck - HP OfficeJet Pro K8600 Printer

just take a soft cotton bud and dip it in after shave lotion or any lens cleaning liquid. Then gently wipe off the stuck paper using the buds. Nothing to worry.

Hi,
Those numbers could indicate a few things.

• First number 3 means you need to check for paper jams.Turn on the printer.Open the scan unit or the front cover,check for any stuck papers inside and remove them.
  
• Check the rear paper tray and remove any stuck papers.
• Number 5 means you need to check the cartridges.Open the scanning unit and check if the cartridges are installed correctly and are the right cartridges.Install the correct FINE cartridges.
• Turn printer off and on again.
  
• If error continues you may have to replace the printhead.
  

Usually this is cuased by something stuck on the scanner. if you have a small peice of dust stuck on it as the paper goes through the scan it thinks that it is all the way down the paper because it seen it all the way through the scan. Clean the scanning surface with a correct cleaner and it should go away and scan normally.

Turn off the Printer
Remove the Rear Access door of printer
Check if the Rollers have any dust/ bits of paper
Clean the rollers with lint free cloth ( upwards just like the paper is picked and rolled )
Close the rear access door
open the front access door
Move the Carriage ( while holds the cartridges ) manually 5-6 times from left to right side
Check if there are any paper pieces stuck
Close the front access door
Turn on the printer..

Re-stack the paper tray and Scuffle the papers before placing them in the tray - Snap the Paper guide to the Paper's in the tray

(1) Slowly pull the paper out, either from the paper source or from the Paper Output Slot, whichever is easier.


(A) When printing from the Auto Sheet Feeder
(B) When printing from the Front Feeder
If the paper tears and a piece remains inside the machine, open the Scanning Unit (Printer Cover) and remove it.
After removing all paper, close the Scanning Unit (Printer Cover), turn the machine off, and turn it back on.
* Be careful not to touch the components inside the machine.
If you cannot pull the paper out, turn the machine off and turn it back on. The paper will be ejected automatically.
(2) Reload the paper in the machine, and press the OK button on the machine.
If you turned off the machine in step 1, all print jobs in queue are canceled. Reprint if necessary.

Scan platform in english is Were you shove the stuff to send ;) ie dirty feed roller, paper detect switch stuck or fragments of paper in original feeding paper path area or feeding stuff too thick or stiff, or if multi document issue it is the pad or roller that sits under the main feed roller...al this is nothiong to do with paper tray full of blanks it is the original feeler area on top..

Same error should occur doing local copy, check feed section/roller

Cheers hope that helps

Check if the paper size selected is same as that of the paper fed in. Clean the sensor in the ADF and remove if any scrap of paper is stuck.

The paper sensor must be checked. Check if there is a speck of paper stuck inside the sensor. Blow with a vacuum cleaner.

These scanners have multiple sensors, that can check if there is a double feed or paper jam. May be one of them is faulty or a small piece of paper is stuck there. Remove/clean this and the scanner will be fine.

This could be because of unclean rollers. The scanner picks paper neat, but images is crooked. This is because paper is stuck on one side and the other side is contnuing on the other, giving it the skew. There may be something sticky on the roller, possibily a left over cellophane tape. Remove it and clean with Isoporpyl alcohol. Dont use solvents.
