Abstract: In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

Abstract: A method for detecting a demountable accessory in an image-forming device is disclosed. The image-forming device comprises a controller, a print platen suitable for receiving a substrate, and a handling mechanism. The print platen has an optical sensor associated therewith adapted to capture an image of an item on the print platen. A first image is captured. The handling mechanism carries out an adjustment action suitable for adjusting the position of the substrate on the print platen. A second image is captured. The first and second images are analyzed to identify any changes and of the captured images is analyzed to detect an accessory identifier. The presence of an item on the platen is determined from the analysis.

Abstract: A printer is disclosed. The printer has a media control system to control the tension in media loaded in a paper path in the printer. A motor in the media control system is characterized to determine a plurality of motor characteristics. The media control system uses the motor characteristics to adjust the control signal to the motor.
