The Permajet ReTac Mounting Spray 400ml is a specially formulated continuously repositionable adhesive mounting spray that can also be used to create a cleaning sheet to clean your printer’s feed/pick-up rollers. Simply spray ReTac to the reverse side of a heavy weight (200gsm +) A4 paper and allow this to dry for 10 minutes minimum, then feed this sheet adhesive side up, using the paper feed button, through your printer and this will remove and pick up all the fibres from the main feed roller that can cause poor paper feed. You can reuse the same sheet and do this process as many times as you like.
