  • Dear Sir / Madam, I bought a Samsung SCX - 4521FG model printer from Canada. I'm not sure whether the D3/G toner cartridge is compatible with my printer. Can you help me with this?

    Toner for SCX-4521 printers

    Unfortunately, we do not recognise the cartridge number you have provided. We only supply cartridges for UK printer models so it's unlikley that the cartridges we stock for the Samsung SCX-4521F printer will work for a printer purchased in Canada. I would recommend contacting Samsung directly with this enquiry.

Samsung SCX-4521F Printer Review

Expert review of the Samsung SCX-4521F printer

Our Verdict:

The Samsung SCX 4521F is the right printer for a home office or for personal use. It is a multifunction device that has the ability to print, fax, scan, and copy documents. This machine is a laser monochrome printer that will easily print up to 20 pages per minute and has a duty cycle of 4,200 impressions per month. The fax machine on the Samsung SCX 4521F is G3 compatible and transmits at a speed of 33.6 Kbps. Scanning is done using a CIS element which has an optical resolution of 600 x 600 dpi. The copier on the Samsung SCX 4521F can copy up to 99 copies at a time and enlarge images by up to 400 percent.


This printer is very handy and can be placed anywhere you have extra room. Its dimensions of 43.68 cm in width, 37.33 cm in depth, and 36.83 cm in height make it easy to find an area for it to be situated. This printer is also very portable and only weighs 10.38 kg. The output tray on the SCX 4521F has a capacity of 50 sheets while the input tray can hold up to 100 sheets. This printer is also easily connected to a computer or laptop using USB or a parallel connection. In addition, Samsung SCX 4521F toner is designed to yield up to 3,000 pages per replacement cartridge.


This printer is built to support a variety of media which include plain paper, cards, labels, envelopes, and transparencies. It is also compatible with many operating systems including Linux, Windows XP, Windows ME, Windows 98, Windows 2000, Mac OS X, and Mandrake Linux. In addition, the Samsung SCX 4521F is certified for use with Microsoft Windows Vista. Another advantage is Samsung SCX 4521F toner comes at a very affordable price, especially here on Cartridge Save. This printer is also energy efficient and operates at an energy-efficient 350 watts. During sleep mode, this printer further reduces its power draw down to 10 watts. Replacing a used Samsung SCX-4521F toner cartridge is easy and requires no specialised tools or knowledge.


This printer is rather noisy during operation at a sound emission level of 55 decibels. During idle, the Samsung SCX 4521F is still loud at 35 decibels. Another downside to this printer is the fax machine has some problems recognizing incoming faxes, which may be a problem for someone who requires a multifunction printer that is reliable.
