How to Refill Your Professional Printer (Toner and Paper)

Properly refilling your professional printer (toner and paper) ensures quality prints and avoids breakdowns. These simple operations, when done correctly, help preserve your equipment’s longevity.

Refilling toner cartridges

When to change?

Warning signs:

• “Low toner” message on screen
• Light or faded prints
• Uneven colours (colour machines)
• Streaks or white areas

Don’t wait until completely empty: Quality degrades before complete exhaustion, and you risk damaging the drum.

Choosing the right toner

Original toner:

• Guaranteed quality
• Optimal compatibility
• Warranty preserved
• Higher price

Compatible toner:

• Lower price (30-50% less)
• Variable quality
• Warranty may be affected
• Choose reputable brands

For important documents, original toner is preferable. For internal drafts, quality compatible can suffice.

Changing process (step by step)

Before starting:

1. Print a status page (to know current level)
2. Have the new cartridge ready
3. Prepare cleaning cloth

Replacement:

1. Open the front cover (or designated access)
2. Locate the toner to replace (by colour if colour machine)
3. Unlock the cartridge (lever or button)
4. Pull out horizontally (avoid tilting)
5. Remove the new cartridge from its packaging
6. Shake gently 5-6 times to distribute toner
7. Remove protective seal (pull the tab)
8. Insert the new cartridge until click
9. Close the cover
10. Wait for initialisation (machine recognises the new cartridge)

Mistakes to avoid

❌ Shaking too vigorously (can cause leaks) ❌ Touching the green drum (fingerprints cause defects) ❌ Forcing insertion (should slide smoothly) ❌ Mixing brands (can cause compatibility issues) ❌ Using expired toner (dried = poor quality)

What to do with old cartridges?

Don’t throw in household waste! Options:

• Manufacturer return programmes (Canon, HP, Ricoh…)
• Retailer collection points
• Specialised recycling centres
• Remanufacturer collection (for recycling)

Paper loading

Choosing the right paper

Document type	Recommended paper
Everyday documents	80g/m² white
Quality presentations	90-100g/m²
Contracts, legal	100g/m²
Envelopes	Specific paper
Labels	Laser-compatible sheets

Avoid:

• Paper that’s too thin (<70g): jams
• Paper that’s too thick (>120g): check compatibility
• Damp paper: jams and quality issues
• Crumpled or folded paper

Storing paper properly

• In original packaging until use
• Horizontal (not standing)
• Dry place (40-60% humidity)
• Room temperature (18-24°C)
• Away from light and heat sources

Loading the main tray

1. Pull out the tray completely
2. Adjust the guides to the paper format
3. Fan the sheets (separate them)
4. Align the stack on a flat surface
5. Place the paper inside guides
6. Don’t overfill (respect maximum marking)
7. Adjust rear guide if available
8. Push in gently

Loading the bypass tray

The bypass (manual tray) is for special formats or media:

1. Open the tray
2. Adjust side guides precisely
3. Insert paper face up (or face down depending on model - check manual)
4. Don’t overload (generally 50-100 sheets max)
5. Select bypass as source before printing

Loading multi-tray machines

For copiers with multiple trays:

• Tray 1: most used format (A4 usually)
• Tray 2: secondary format or reserve
• Tray 3/4: high capacity for high volumes
• Bypass: special formats, thick paper

Configure default tray preferences in machine settings.
