HP 3550 manual Labels, Heavy paper

NOTE

NOTE

CAUTION

Adhere to the following guidelines to help ensure proper printing on envelopes and to help prevent printer jams:

●Do not load more than 10 envelopes into Tray 1.

●The weight rating of envelopes should not exceed 90 g/m2 (24 lb bond).

●Envelopes should be flat.

●Do not use envelopes with windows or clasps.

●Envelopes must not be wrinkled, nicked, or otherwise damaged.

●Envelopes with peel-off adhesive strips must use adhesives that can withstand the heat and pressures of the printer’s fusing process.

●Envelopes should be loaded face-down with the top of the envelope to the left, and the short edge feeding into the printer first.

In high humidity environments, envelopes should be printed long-edge first to prevent them from sealing during printing. For long-edge printing, envelopes should be loaded long edge first, face down. See Printing envelopes from Tray 1 to change the printer driver’s envelope orientation.

Labels

In either the application or the printer driver, select Labels as the media type, or configure Tray 1 for labels. See Configuring trays.

When printing labels, use the following guidelines:

●Verify that the labels’ adhesive material can tolerate temperatures of 190° C (374° F) for 0.1 second.

●Verify that there is no exposed adhesive material between the labels. Exposed areas can cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can also cause damage to printer components.

●Do not re-feed a sheet of labels.

●Verify that labels lie flat.

●Do not use labels that are wrinkled, bubbled, or otherwise damaged.

Heavy paper

●Any tray will print most heavy media that does not exceed 105 g/m2 (28 lb bond).

●Use cardstock only in Tray 1 135 g/m2 to 166 g/m2 (50 to 61 lb cover).

●In either the software application or the printer driver, select HEAVY106 g/m2 to 163 g/ m2 (28 to 43 lb bond) or CARDSTOCK 135 g/m2 to 166 g/m2 (50 to 61 lb cover) as the media type, or print from a tray that is configured for heavy paper. Because this setting affects all print jobs, it is important to return the printer back to its original settings once the job has printed. See Configuring trays.

In general, do not use paper that is heavier than the media specification recommended for this printer. Doing so can cause misfeeds, paper jams, reduced print quality, and excessive mechanical wear. However, some heavier media, such as HP Cover Stock, can be safely used.
