HP 72SR manual Manual Calibrations

Media Feed This calibration allows you to calibrate the accuracy of the media advance. Inaccurate media advance can result in blank spaces between print swaths (too much advance) or overlapping swaths (too little advance). The Media Wizard stores this value by media type, and displays a media feed number (MFN), which you can record for subsequent entry.

The media feed number enables you to quickly specify a known good media feed setting without recalibration. For example, you could keep a list of media feed numbers by media type, or by media type and full, half, and nearly empty supply rolls.

Tip	You can also adjust the media advance while a print
	job is printing. Repeatedly press the increase
	advance or decrease advance button shown on the
	control panel to eliminate blank spaces or overlap
	between print swaths. When you do this, the media
	feed number displayed on the control panel
	changes accordingly.

1.On the Manual Calibrations menu, highlight Media Feed (which is highlighted by default).

2.Press the  (Menu In) key to select the option.

◆Stitch pattern — First, allow the printer to print the fol- lowing number of swaths, depending on the mode you want to calibrate:

◆16 swaths in Quality mode, or

◆8 swaths in Production mode, or

◆4 swaths in Billboard mode

Next, press the , key to increase the advance until you see blank spaces between swaths.

Finally, press the ) key to decrease the advance until the blank spaces are eliminated, but avoid dark lines between swaths (which indicate overlap). This method allows for the tendency of the media advance to gradu- ally decrease as the size of the supply roll decreases.

◆34-inch calibration — prints a 34-inch test pattern so you can verify its length with an accurate metal ruler. Cut the pattern from the media web, then measure and adjust the media advance as needed until the pattern is exactly 34 inches long.
