Reliability Builders   
A Heavy-Duty Productivity Booster
A precision-engineered Multi-Feed 
Detection System on the MX-M1204 
and the MX-M1054 employs ultrasonic 
technology to detect and diagnose 
misfeeds from the document feeder 
and the paper feed section of the 
paper trays.
Multi-Feed Detection System
For reliable output of two-sided copies and prints, the MX-M1204/ 
M1054/M904 provides built-in curl correction to uncurl paper just after 
transfer. And for added stability, the optional Curl Correction Unit uses 
top and bottom rollers to apply pressure to convex and concave curls, 
preventing paper from warping before it goes to the finisher.
Curl Correction
While the MX-M1204/M1054/M904 holds a generous 3,100 sheets 
of paper, this standard capacity can be expanded to meet the 
needs of high-volume jobs. Adding an optional 500-sheet 
Multi-Bypass Tray and two 5,000-sheet (2,500 x 2) Large Capacity 
Trays boosts capacity to 13,500 sheets. And when a tray runs out 
of paper, the Auto Tray Switching function automatically 
switches to another tray with the same-sized paper. 
The MX-M1204/M1054/M904 can scan both pages of two-sided B/W 
and colour documents in one efficient pass. Capable of scanning 
one-sided A4-size (8
1
/
2
" x 11") documents at 120 opm* and two-sided 
A4 documents at 200 opm*, the 250-sheet DSPF (duplex single pass 
feeder) minimises paper misfeeds and brings fast, reliable operation. 
*Originals per minute (when feeding A4-size documents at 200-dpi resolution) 
Built to meet the rigorous, high-volume demands of offices, copy rooms, 
CRD, and corporate data centers, the MX-M1204/M1054/M904 delivers 
B/W copying and printing at the impressive speed of 120, 105, or 90 
cpm/ppm. Advanced technology, integrated network scanning, and 
flexible configurations expedite job processing and streamline document 
workflow like never before. And to bring productivity and reliability 
where it’s needed most, this high-volume workhorse boasts a 1TB hard 
drive and 5GB of standard memory.
The Triple Air-Feed System on the optional 5,000-sheet MX-LC13 Large 
Capacity Trays reliably separates and feeds in paper to facilitate jam-free 
operation and minimise downtime. Capable of supporting a wide range 
of paper types, this system employs air-feed technology and three 
precisely directed air flows for maximum reliability and proper paper 
handling.  
Intermediate Toner Hopper for 
Continuous Runs
To protect the MX-M1204/M1054/M904’s enhanced data-handling 
capability and bring peace of mind, the optional Mirroring Kit 
provides hard disk backup. In the event that one hard disk is 
damaged, the data will be saved safely on another disk, ensuring 
continued operation.
Mirroring Kit
The developer unit in the MX-M1204/M1054/M904 employs a forced-air 
cooling system to prevent excessive heat build-up. This enables the unit 
to maintain consistent image quality, even in high-volume printing 
environments.
Developer Cooling Systems
A highly rigid support frame isolates 
and protects critical machine 
components in the MX-M1204/ 
M1054/M904, ensuring increased 
durability and reliability. The unit can 
withstand heavy use in locations where 
rapid, high-volume output is 
demanded.

Large Paper Capacity
The MX-M1204/M1054/M904 accommodates a wide range of paper 
sizes—from A5R (5

/2" x 8½"R) to SRA3/A3 wide (12" x 18")—and 
can provide full-bleed copying and printing on SRA3 paper. To  
further expand the range of printing applications, the MX-M1204/ 
M1054/M904 supports paper weights up to 300 g/m

Versatile Paper Handling
High-Efficiency Scanning 
A Winning Combination of 
Speed and Power
With an optional High Capacity Stacker, 
the MX-M1204/M1054/ M904 can 
accommodate up to 5,000 sheets, 
expandable to 10,000 sheets when two 
stackers are connected. Each stacker 
comes with a roll-out Paper Cart for 
effortless and efficient transport.
High Capacity Stacker
The MX-M1204/M1054/M904 was designed to maximise reliability and minimise downtime. Sturdy construction and features for 
smooth, uninterrupted paper feeding and printing ensure stable high-volume output and dependable operation. 
Productivity is the key to success in high-volume environments. On the MX-M1204/M1054/M904, speedy output, smooth scanning, 
expandable paper capacity, and versatile paper handling streamline document workflow and put productivity on the fast track. 
Particularly convenient during toner cartridge replacement, an unlikely 
paper jam, and other operations, full front access to all key machine 
components ensures easy maintenance—and maximum uptime.
Full Front Access 
The optional Status Indicator provides 
diagnostics via green and red LED lights 
that are clearly visible from a distance. 
The green light remains lit while a job is 
being executed and blinks while 
document data is being read. The red 
light blinks or lights up to indicate an 
error that may or may not prevent normal operation. 
Status Indicator
To boost information sharing and distribution, processed job data can be 
saved in designated folders on the MX-M1204/M1054/M904’s built-in 
hard disk for instant recall, printing, or sending at a later time. Data for 
frequently used template documents can also be saved on the hard disk, 
enabling quick and easy output for enhanced productivity.
Document Management on the Hard Disk
When two MX-M1204/M1054/M904s are connected to the same office 
network, they can be used simultaneously to double copy/print output to 
up to 240 cpm/ppm. Large-volume jobs can be completed with ease, 
ensuring that tight deadlines will be met.
Network Tandem Output
Thanks to an intermediate toner hopper, there’s no need to stop the 
MX-M1204/M1054/M904 during large-volume copy/print jobs when the 
toner cartridge needs changing. The MX-M1204/ M1054/M904 can use 
toner from the toner hopper to continue printing while the empty toner 
cartridge is replaced with a new one.
