2016-04-10 The replacement printer had arrived. As its fuser was much worse than the other one, I exchanged them. Now printing is jamless. :-) But a new error came up. When I printed a PDF containing a large image, the printer printed a page with the following error mes- sage instead: ERROR: limitcheck OFFENDING COMMAND: image Some research brought up, that the problem appears to be the conversion from PDF to PS when the image size overfloats the max- imum possible image size allowed in PS. I circumvented the problem by running pdftops(1) on the client and sending the resulting PS to the printer. This also is much faster than the internal PDF-to-PS conversion of CUPS. http://marmaro.de/lue/ markus schnalke
