All our plain paper systems function perfectly with paper corresponding to DIN 19309, "paper for copying purposes". This standard covers normal paper as well as recycled paper.
We recommend paper corresponding to DIN 19309 for a trouble-free operation of our systems. This is one of the conditions for the environmental marks "Blue Angel" and "Swan Label".
Lower paper quality can be responsible for paper jams and shorter maintenance intervals. Paper not corresponding to DIN 19309 is characterised by extremely short strings and can be very resinous and dust-laden.
Please ask your paper supplier for advice, and support our environment by choosing the right kind of paper.
