The number of the printers on PC increases when USB is connected.5.1.2 Adjustment of Fixing System5.1.2.1 Checking the Nip Width (fixing pressure roller) 0014-2866/ i-SENSYS LBP5360 / i-SENSYS LBP5300Do not check the nip width in wrong order. The fixing sleeve breakage mayoccur, if you do not follow the procedures below.An incorrect nip width may cause the faulty fixing. Check the nip width byfollowing the procedure below if poor fixing image defect occurs. Replacethe fixing unit if the nip width is out of specification, since the nip width ofthe fixing unit is not adjustable in this printer.1) Make an all solid black print of A4 or Letter size using an EP cartridgesame as for this printer, and take the print to the customer's site.2) Place the solid black print, with the printed side facing UP, in the cassetteof the printer.3) Press the test print switch.4) Open the upper cover as soon as the leading edge of the paper appears inthe delivery slot. Leave it for ten seconds.5) Turn OFF the printer and take fixing unit from the printer. Then take thepaper out from the fixing unit.6) Measure the width of the glossy band across the paper and check that itmeets the requirements as shown in Figure.- Center (a): 8mm +/- 1mm- Difference between right/left and center (a-b, a-c): 0mm to 1mm- Difference between right and left (|b-c|): 1.5mm or less[1][2]
