Install Labels and Ink Cartridges in the J7300The J7300 uses Brady Labels that are equipped with smart-cell technology that enables the printer to recognize the type of label installed and automatically set many label formatting details. Only use labels that have the Brady Authentic logo. 
The J7300 printer utilizes pre-sized, circular, edge notch, continuous and gap label supplies. The maximum width of labels is 4.25 in. (10.8 cm) without the liner or 4.13 in. (19.49 cm) with the liner.Install LabelsIf the tray accessory was purchased, top the printer up and slip the tray under the printer between the four anchor posts. The tray catches the labels after they are cut.
- Open the label cover.
- Press the yellow Media Guide Lever and move the guide left to fit the label roll.
- Remove any shipping tape from the label supply roll to ensure that it can unroll freely, making certain that no adhesive portion is exposed.
Important: Exposed adhesive surface can attach itself to the inner workings of the print mechanism and cause a jam.
- Hold the label roll with the labels coming off the top of the roll, the smart-cell on the right and the handles on the sides pointing up.
- Hold the handles and place the label roll into the supply holder.
- Place the leading edge of the label between the adjustable media guide (left side) and the stationary guide on the right side of the printer.
- Move the media guide to where it barely touches the edge of the label supply. Guide the labels forward until it is automatically fed through the printer. The printer will sense the label and automatically feed it through the printer. If the printer fails to feed the label supply, remove and reinsert the label roll then press the feed button on the screen to manually engage the feed roller.
Note: To ensure that the labels are fed straight be sure to push the label supply into the printer quickly until the entire front edge of the label is touching the feed roller. For wider labels, use both hands to feed to maintain even forward pressure while you are pushing the labels into the printer. Removing Label Supply
