Important
• When the printer is turned off, mass storage mode is deactivated and any files in the mass storage area
are deleted.
• This feature supports “.bin”, “.blf”, and “.jpg” files. Do not use other file formats with this feature.
• Do not create folders in the mass storage area. If a folder is created, files in the folder will not be executed.
• The capacity of the mass storage area is 15.8 MB.
• If multiple files are copied, the order that the files will be executed in cannot be guaranteed.
• Wi-Fi and Bluetooth are not available while the printer is running in mass storage mode.
• Do not access other files in the mass storage area when executing a copied file.
Print JPEG Images 4
Image data (JPEG) can be printed without using the printer driver.
Note
• JPEG images can be printed using the mass storage feature.
• The Object Push Profile (OPP) is used for printing via a Bluetooth connection.
• This printer will convert a color JPEG image to a ‘Black & White’, image using a dithering process.
• When sending a JPEG image that is already ‘Black & White’ this dithering process may make your printed
image fuzzy.
• To improve the image quality, try to turn off any preprocessing of the JPEG image.
Only JPEG images can be printed. (Limited to files with the .jpg extension.)
The maximum file size is 15.8 MB.
The maximum resolution is as follows:
Height Width = 24000 832 dots
If these limits are exceeded, the data received by the printer will be discarded and not printed.
Print is at 1 pixel = 1 dot.
This printer performs binary processing (simple binary) to print the image.
The image is printed with the height-to-width proportion of the received data.
Remote Update (RJ-4250WB Only) 4
The Remote Update feature allows for the semi-automatic update of the printer's settings with a simple
connection to a network folder where the update files reside. For more information about Remote Update,
see Remote Update (RJ-4250WB only) on page 43.
