Many digital workers struggle with two things – banding and difficult paper feeding. They waste a lot of ink with cleaning cycles to try and cure banding – not always successfully. The simple wiping action of the printer mechanics can fail to shift built up ink deposits, especially if the machine has been idle for some time, or if the type of ink being used is changed. They sometimes also scatter a lot of inks around inside the machine. Many suffers from banding fail to realise the critical importance of the roller feed system. After each pass of the print head, the paper is fed forward a PRECISE amount. If the roller surface should slip even slightly on the paper, its feed distance is slightly shortened giving a marginal overlap with the previous head pass. The double ink layer here causes a banding effect. Many inkjet papers have a coating to receive the ink which deposits over time a slippery layer on the print rollers. Sometimes the effect of this is obvious with paper refusing or being difficult to feed into the machine. Sometimes the effect is less obvious with very slight banding taking the edge off print performance. Clenstech© provides a duo-pack of two specially developed cleaners. One is for the head, one for the rollers. Both have unique additives to help prevent future build-up problems. Simple, but very effective.
