HP 72SR manual Printer automatically locates the right and left

6.Ensure that the media is rolled onto the supply spool evenly, without “telescoping” to one side.

7.With your right hand, feed the leading edge of the media into the printer’s pinch rollers and hold it in place until the following step.

If loading 72 inch media, see “Loading 72-Inch Media” on page 3-20 for loading tips.

Note	The printer automatically locates the right and left
	edges of the media, so it is not necessary to align the
	media edges to a reference mark on the platen.

8.With one hand, press the Media Advance button to advance media a few inches (several centimeters), until the media is approximately halfway between the pinch rollers and the postheater (middle of the platen).

The Media Advance button is located to the left of the postheater, on the rear of the printer next to the OHS.

9.While holding the left collet stationary, repeatedly press and release the Media Advance button several times, until the supply-side media web is tight with no wrinkles.

This causes the grit rollers to grip the underside of the media, eliminating tension variations across the width of the media.

Ensure that the right and left edges of the media web are perpendicular to the sides of the printer, that the tension appears uniform across the media web, and that the media is not unrolling unevenly (“telescoping”) from the supply spool.

If the media is telescoping, reverse the media out of the pinch rollers and repeat steps 8 and 9.

Note These checks ensure that the tension is uniform across the width of the media. This is critical to trouble-free printing.
