An image forming apparatus having an image forming apparatus and a first housing is provided. The first housing has a top cover, a front cover, a side cover, a first guide, and a second guide. The front cover has a front wall having a first outlet port and a first upper wall. The side cover has a first side wall having a second outlet port and a second upper wall. The first guide guides liquid entering the first housing to the first outlet port and is connected to the front wall. The second guide guides the liquid entering the first housing to the second outlet port and is connected to the first side wall.

An image forming apparatus, having a main body housing including an air outlet opening, a photosensitive drum, a fuser to thermally fix toner transferred from the photosensitive drum to a sheet on the sheet, a fan to generate an airflow toward the air outlet opening, and a controller, is provided. The controller is configured to, in a continuous stage of printing continuous from a beginning stage, count a cumulative printed page number being a cumulative number of pages printed by the image forming apparatus, in a case where the cumulative printed page number is smaller than a first page number, control the fan to rotate at a first speed, and in a case where the cumulative printed page number is equal to or larger than the first page number, control the fan to rotate at a second speed, the second speed being higher than the first speed.

An image forming apparatus includes a housing, a door, an inlet, a primary power source, a secondary power source, a primary interlock switch, and a secondary interlock switch. The housing has an opening. The door is hinge-coupled to the housing by a hinge, and opens and closes the opening. The inlet is provided near the hinge. The secondary power source is provided farther from the inlet than the primary power source. The primary interlock switch is provided on a primary electric circuit between the inlet and the primary power source, and is turned off when the door is opened. The secondary interlock switch is provided on a secondary electric circuit between the primary power source and the secondary power source, and is turned off when the door is opened. The primary interlock switch is disposed closer to the inlet than the secondary interlock switch.

An information processing apparatus includes a processor configured to display an operation screen for receiving an operation regarding setting information of an image forming apparatus that operates in association with the setting information with optimum values changing depending on external factors on a display device and receive an operation on the operation screen, in which the processor is configured to display a creation screen that is one of the operation screen and is used to newly create the setting information, on the display device, receive an input of a reason for creation of the new setting information on the creation screen and specify an item to be set corresponding to the received reason for creation among setting items in the setting information, and display the specified item on the operation screen to be identifiable with respect to other setting items.

A sheet discharge device includes a sheet discharge portion, a sheet loading portion, and a stopper mechanism. The stopper mechanism includes a first stopper supported pivotably to a first retraction position and a first restriction position, a second stopper that is movable to a first position at which the second stopper is housed along a downstream end part of the sheet loading portion and a second position apart from the first position to a downstream side in a sheet discharge direction and is supported pivotably to a second retraction position and a second restriction position, and a link mechanism connecting the first stopper to the second stopper. When the second stopper is disposed at the first position, the first stopper is disposed at the first restriction position, and when the second stopper is disposed at the second position, the first stopper is disposed at the first retraction position.

An image forming apparatus is provided with a printing device, a sheet conveyance path, a protective cover, a swing member, and a biasing member. The sheet conveyance path includes an upper guide portion and a lower guide portion. The swing member is supported inside a main body and can swing upward from a standard position. The biasing member biases the swing member to the standard position. The swing member includes the upper guide portion. The protective cover includes the lower guide portion and a contact portion. The contact portion pushes the swing member upward when the protective cover pivots in an outward position from a closed position. The protective cover can pivot from the closed position to an open position as the contact portion pushes the swing member upward.

Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to adjust a velocity of a development unit within the printing device, a memory resource, and a controller in communication with the memory resource to determine an average usage condition of the printing device, wherein the average usage condition is based on at least one of a print coverage and a quantity of pages printed by the printing device, and adjust a velocity of the development unit based on the average usage condition.

An evaluation device evaluates an image clarity of a print image. The evaluation device includes: an object that is projected onto a measurement surface of a recording medium; an illuminator that makes the object projected onto the measurement surface; an imager that images the measurement surface on which the object has been projected to obtain image data; and a hardware processor that, based on a distribution of parameters related to a brightness of the image data, quantifies a degree of the image clarity into a numerical value and defines the numerical value as an evaluation value of the image clarity.

An automatic document feeder includes a media path to route media through the automatic document feeder, at least one media tray to one of supply the media to the media path and receive the media from the media path, and an automated media tray extender at an end of the media tray, the automated media tray extender to be positioned based on a presence of the media in the media tray.

An image forming system includes: an image former that forms an image; a stacker that stacks a recording medium on which an image has been formed by the image former and which has been discharged from the image former; a lifter that raises or lowers the stacker between a stacking position where the recording medium is stacked and a lower position located below the stacking position; a recording medium detector that detects the recording medium stacked on the stacker; and a hardware processor that controls driving of the lifter so as to lower the stacker from the stacking position to the lower position when it is determined that the recording medium is on the stacker on the basis of a detection result of the recording medium detector within start-up time from a time when power is switched on to a time of shifting to an image formable state.
