Summary: The Business Case in Short
The dream of every reprographics manager: You load the printer with jobs at 5:00 PM. You turn off the lights. You go home. The next morning at 8:00 AM, a stack of 300 perfect prints and folded drawings is ready. The reality at many companies: You walk in at 8:00 AM. The printer says “Error: Paper Jam” or “Out of Ink”. There is 1 crumpled drawing. The other 299 have not been printed. Consequence: Panic. Stress. Customers calling about their drawings. You spend the whole morning cleaning up the mess. True “Unattended Printing” (onbeheerd printen) requires more than just a printer. It requires the right combination of hardware, software, and accessories.
The 3 Pillars of Night Production
1. Ink Supply (Dual Ink Tanks)
A standard printer stops when the cartridge is empty.
- Solution: Professional machines (such as the HP PageWide XL or DesignJet XL 3800) have two tanks per color (Intermediate Tanks) or space for massive cartridges (e.g., 1 or 5 liters).
- If tank A is empty, it switches seamlessly to tank B while printing.
- So you never have to worry about an empty cartridge stopping the job halfway through the night.
2. Paper Swap (Auto-Roll Switching)
What if the roll runs out?
- A machine with 1 roll stops.
- A machine with 4 or 6 rolls (PageWide XL 8200) switches automatically.
- Is Roll 1 (A0 Bond) out? It takes Roll 2 (A0 Bond).
- Is the drawing A1 instead of A0? It takes Roll 3 (A1 Bond).
- This smart switching guarantees that the queue is processed, regardless of paper consumption.
3. Reliable Finishing (Folding & Stacking)
This is where it most often goes wrong. Paper gets stuck in the folding machine or falls off the stacker.
- Online Folder: An integrated folding machine (such as the HP F-series or Esstefold) communicates with the printer.
- If a folding error is imminent, the printer pauses immediately so the entire roll isn’t pimped into a “paper harmonica”.
- High Capacity Stacker: As discussed in a previous blog: you need a tray that can handle 500 sheets without jamming.
Business Fundamentals: The “Lights-Out” ROI
Why invest in these expensive options? Because your machine then earns money while you sleep.
- Capacity Expansion: You extend your workday from 8 hours to 16 or 24 hours without extra staff (no night shift surcharge).
- Speed: You can deliver immediately in the morning. The courier can depart at 8:30 AM.
- Earnings Model: This enables you to take on large tenders (“I need 500 sets tomorrow”) that your competitor with their small printer would have to say “No” to.
Technical Tip: The “Job Queue” Management
Software such as HP SmartStream is crucial.
- You can set: “Print all A0s first, then all A1s” (minimizes roll swaps).
- Or: “Hold jobs that require paper that is not loaded” (Blocking prevention). This way, the entire queue doesn’t stop if there’s one exotic size in between; the printer skips it and does the rest.
Europlan Service: Preventive Maintenance
For night production, the machine must be 100% reliable.
- Dust in the sensors is the enemy.
- Our maintenance contracts include preventive cleaning of paper paths and sensors.
- We monitor your machine remotely (“Remote Monitoring”). If we see that a roll motor is showing wear, we replace it before it jams at night.
Conclusion: Trust is Good, Certainty is Better
Unattended printing is not magic; it’s engineering. With the right configuration, the printer becomes your most reliable night worker.
