A printing apparatus is disclosed herein. The apparatus comprises a platen to hold a media thereon, the media moveable along a media path direction; a displacement mechanism to move the media over the platen and along the media path direction; a media advancement sensor; and a controller. The controller to determine a media advancement prediction based on an operational parameter of the displacement mechanism; determine a read media advancement corresponding to the media advancement prediction; determine a sensor reading failure based on the media advancement prediction and the read media advancement; determine that the media advanced a distance corresponding to the media advancement prediction if the sensor reading failure is detected; determine that the media advanced a distance corresponding to the read media advancement if the sensor reading failure is not detected; and to adjust the position of the media by controlling the displacement mechanism to move the media based on the determined media advanced distance.

Adjusting media positions based on read media advancements and predictions

According to some examples, a skew detection device comprises a first roller rotatable around a first axis, a second roller rotatable around a second axis, a first sensor, and a second sensor. The first sensor measures a first rotation parameter from the first roller and the second sensor measures a second rotation parameter from the second roller. A movement of a print media over the device rotates the first contact roller and the second roller, and a controller determines a skew of the print media based on the first and second rotation parameters captured by the first sensor and the second sensor.

Skew detection

According to an example, a media loading device may comprise a motor and a leading-edge sensor. The motor may rotate a media roll having a leading-edge in a winding direction and unwinding direction, the motor being controlled by a processor. The leading-edge sensor may comprise a pivot arm and a detecting element. The pivot arm may contact the media roll and the detecting element may issue a leading-edge presence signal to the processor upon contact between the detecting element and the leading-edge occurs.

Media loading devices

A printing device and method is described comprising: controlling movement of a printing medium along a printing medium path to position the printing medium relative to at least one printhead to allow printing on the printing medium by the at least one printhead; and applying a plurality of respective elastic forces in a direction substantially perpendicular to the printing medium path, wherein the respective elastic forces are applied by a plurality of elastic elements of a modular assembly arranged laterally across a width of the printing medium path, wherein the printing medium acts against the elastic forces of the respective elastic elements of the modular assembly.

A vacuum system for a printing apparatus comprises a structural member. The structural member comprises a fluid conduit to be connected to a vacuum source. The vacuum system comprises a coupling. The coupling comprises a first end and a second end defining a fluid passage therebetween. The coupling is attached to the structural member at its first end thereby connecting the fluid passage of the coupling to the fluid conduit of the structural member. The second end of the coupling comprises a resiliently deformable material. The second end is to connect to a vacuum chamber of a print unit.

Printing apparatuses with vacuum systems

According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.

Bi-directional cutting modules

Disclosed is a cutter module to be used with a printing apparatus. The cutter module comprises a blade driving mechanism; and a rotary cutting blade driven by the blade driving mechanism. The blade driving mechanism comprises: a clutch mechanism selectively to enable the blade driving mechanism to drive the rotary cutting blade in a forward cutting direction or a backward direction. Also disclosed is a printing system comprising the cutter module and a method to be used with the cutter module.

Forward and backward rotation of printer cutters

A printable medium support for a printer comprises a support element to support a printable medium, wherein the support element is movable between a protruding configuration to support the printable medium, and a retracted configuration in which the support element is at least partially retracted in a first direction. The printable medium support comprises an actuating element to move the support element between the protruding configuration and the retracted configuration.

Retractable printable medium support

A cutter assembly for a printable medium comprises a cutter to cut the printable medium, a trench adjacent to the cutter, and a trench cover, the trench cover at least partially covering the trench. The trench cover is movable between a supporting configuration to support the printable medium, and an open configuration to receive portions of the printable medium in the trench. The cutter assembly comprises an elastic element for biasing the trench cover towards the supporting configuration. The cutter comprises an engaging element and the engaging element engages the trench cover to move the trench cover from the supporting configuration towards the open configuration.

Cutter assembly with movable trench cover

A printer comprises at least one longitudinal cutter module to cut a print medium in a longitudinal direction with respect to a print media advance direction. The printer comprises a controller to position the longitudinal cutter module along a direction perpendicular to the print media advance direction. The controller is to receive a full-bleed print job and in response to receive print job to position the at least one cutter module along the direction perpendicular to the print media advance direction. The longitudinal cutter module is positioned by the controller to longitudinally cut the print medium.

Cutter module positioning for full-bleed printing

A cutter is positioned at a cutting position according to a virtual coordinate system. Media is cut at the cutting position using the cutter to create a cut. The actual location of the cut in the media is detected and the virtual coordinate system is calibrated based on an offset between the cutting position and the actual cut location.

Cutter calibration

In An example cutting module comprises a housing to engage the cutting module with a drive shaft, a cutter engaged with the housing, and a drive system engaged with the housing. The cutting module movable along the drive shaft laterally to a media path, the cutter cuts media along the media path, and the drive system may lock when the drive shaft rotates in a second drive direction such that the cutting module moves with the drive shaft.

Cutting modules

An example media handling system provides a print media () along a media path () and at least part of the media handling system includes an adhesive material for locating the print media () on the at least part of the media path ().
