1. Office colour multifunction machines

Recent history and development

Until 2005 the majority of colour printers were specialist machines capable of limited black output because of high black & white running costs.
Konica Minolta’s Bizhub range in the last 3 years offers users black & white running costs as economical as black & white only machines coupled with colour reproduction previously available on equipment costing in excess of £20,000

2. “Full colour” - Defining the term

• Konica Minolta machines are “full colour”. This has a double meaning:
a) The print reproduction is capable of the full gamut of colour without compromise
b) The machine can be used to print, copy, scan every page if required i.e. up to 100% of all output
• Some machines are described as ‘colour capable’ or ‘business colour’ of ‘spot colour’. There can be restrictions on the amount of colour throughout and/or the range of colour printed


3. Colour and Black & White relationship

• Cost per print and how it is separated
• How black is produced – integrity of black is a good measure of a colour machine


4. RIP’s - How colour originals are made into printed image

• Konica Minolta “Emperon”
• E.g. Fiery
 Separate IP addresses
 On-screen workstation for colour multifunction


5. Scanning in colour

• User selectable dpi
• Colour originals can be scanned in black & white
• Full range of formats: JPEG, TIFF, PDF, compact PDF


6. Photocopying

• Typical applications are newspapers, magazines and archived materials
• The ability to reduce the background through the panel

• Use of bypass
• ‘Whiteness of paper’

8. Typical Originals

• PowerPoint

• Corporate colours/logos
• Specific Pantone
 Note: PBS welcome prospective users to send samples (e.g. PDF) for us to print out and return to you for your assessment of the quality.


10. Multifunction and Laser Printers compared

• MFP’s have longer yield consumables than laser printers
• The cost of the consumables expressed as a material cost per page is much lower
• The service charge (price per page) is lower on a MFP
• Image quality on a MFP is crisper and more vibrant


11. Machine Consumables

• Each machine has 4 separate toners
• Machine uses image units, fuser unit, waste collector, and transfer belt
