A height adjuster moves a platform along a cart frame, and the platform contacts an alignment stop when the platform is in a loading position on the cart frame. Platform slots are connected to the platform, and the platform slots are sized and shaped to match the size and shape of linear projections of a replaceable printing module. Clamps are sized and shaped to connect to connection points of a printing device and align the cart frame to the printer frame. The platform slots are positioned by the platform to be aligned with housing slots of the printing device when the clamps connect the transport cart to the printing device, and when the platform contacts the alignment stop (and is in the loading position) this allow the replaceable printing module to be transferred between the transport cart and the printing device.

A mount apparatus to be mounted on a top surface, in a vertical direction, of a main body of an image forming apparatus configured to form an image on a sheet, includes a latch member extending toward the main body from a surface facing the top surface of the main body and being rotatable around a rotational axis extending in a direction along a direction orthogonal to the vertical direction, and a biasing member configured to bias the latch member in a predetermined rotation direction. The latch member is inserted into the main body through an opening that is provided on the top surface of the main body and is engaged with the main body by a biasing force of the biasing member in a state where the mount apparatus is mounted on the main body.

The present teachings relate to various embodiments of a gas enclosure system that can have a particle control system that can include a multi-zone gas circulation and filtration system, a low-particle-generating X-axis linear bearing system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. Various components of a particle control system can include a tunnel circulation and filtration system that can be in flow communication with bridge circulation and filtration system. Various embodiments of a tunnel circulation and filtration system can provide cross-flow circulation and filtration of gas about a floatation table of a printing system. Various embodiments of a gas enclosure system can have a bridge circulation and filtration system that can provide circulation and filtration of gas about a printing system bridge and related apparatuses and devices. Accordingly, various embodiments of a gas circulation and filtration system as disclosed herein can effectively remove both airborne particulate matter, as well as particulate matter generated proximal to a substrate during a printing process. As such, various embodiments of a gas circulation and filtration system in conjunction with various embodiments of a gas purification system of the present teachings can provide for a controlled manufacturing environment resulting in a high-yield of OLED various devices.
