Ready when you are

The new bizhub i-Series is fast and always ready to help you out. Fast warm-up times get you started in 17 seconds or less, while speedy First Copy Out Times, or First Print Out Time for the bizhub 4701i, put printed materials in your hands in moments.

Easy-to-use paper trays

The lightweight paper trays on the new bizhub i-Series open and close smoothly with a light press or pull motion. Moreover, in the case of a paper jam, the paper trays can be easily removed to fix the jam.

High-quality output

Print at 1,200 dpi resolution for excellent reproduction of small font sizes and detailed design. Outstanding resolution capabilities ensure enhanced legibility of documents and sharp reproduction of fine lines.

Printing at 1,200 dpi slows printing speed.

Non-image Area Erase

Often times, making copies from odd-size or thick materials can produce unwanted shadows on the outside of the image. Non-image Area Erase on the bizhub 4751i and 4051i automatically detects the document area and eliminates the shadow or dark areas surrounding the image. This is ideal for scanning receipts and multiple pages from thick books with the document cover open.

Custom-size paper is just as easy

The new bizhub i-Series offers compatibility for custom-sized paper in the front-loading main paper tray. The tray can hold up to 20 post cards or 30 envelopes for easy printing without having to use the side-loading manual feed tray, saving space and increasing efficiency.

Paper compatibility

Both the main paper tray and the manual feed tray can feed a wide range of paper weights from 60 to 210 g/m²

Automatic copy area detection

Non-standard-size documents placed on the platen glass or in the ADF of the 4751i and 4051i are automatically measured, and the size can be registered and saved for future use. This function is ideal for businesses that constantly handle odd-size documents such as tickets or vouchers.

Print from the in-panel web browser

Websites can be displayed on the operation panel and printed directly. Specify pages of web-hosted PDF files to print out only what you need. Convenient for quickly printing maps or company contacts before heading to an appointment.
